Other sandwiches I love that don’t require heating up are Egg Scallion and Tomato SandwichGrilled Chicken Sandwich with Avocado and Tomato, and my favorite… Roast Beef, Arugula and Shaved Parmesan.

To make the tuna salad quickly, I throw all the vegetables in my chopper and pulse a few times. If I am eating one sandwich, I keep the rest refrigerated for the next day. Easy peasy!

I grew up with avocados in my home way before they became popular here in the States, and squeeze them into my diet every chance I can. Avocados are a regular part of a South American diet, and my mom always served them along side a hearty bowl of hot soup or rice and beans. Avocados are also good for you, loaded with heart-healthy fats and antioxidants. They are a great addition to this tuna sandwich!

  1. Delicious!! I love the idea of bulking up my tuna with extra veggies (and less mayo). This is a great quick and easy lunch to feel good about eating.

  2. Very tasty!  I liked the crunch.  I topped mine with  micro greens.

  3. This was AMAZING! I don’t think I will eat tuna any other way! Huge hit in my house! Thank you!

  4. Hi,

    What do you find to be the best brand of multi-gain bread?

  5. Nice refreshing tuna salad. I found a “slimcado” at the store with less fat, and I don’t use as much on each sandwich, maybe 1/2 ounce, and had pretty mulit color mini tomato, was pretty.
    I did add something I found that is called Oasis roasted red pepper hummus which says only 28 calories per 2 tabs, and I added a tab of that too, perks it up a bit to me. I also used a whole 2.6 ounce pack light chunk tuna for each of two sandwiches, open faced. And with light bread the whole thing was only about 191 calories even with more tuna. I think I saved a few calories with the bread type and slimcado perhaps.

  6. i loved this; I ended up using a little more light mayo than the recipe called for because it was a little dry but after that it was perfect. I made with the sandwich thins as kind of a toasted sandwich…so quick and easy and delicious for lunch! Love the idea to add carrots to the tuna salad; i’ve never done that before!

  7. Very tasty!

  8. Super simple. Delicious. Hubby says he could have this every day for lunch. 🙂

  9. What chopper did you use?

  10. I made some alterations to this:
    1 serving of Leftover mushroom ceviche with juice (excluded the red wine vinegar), 10 baby carrots, fresh cilantro, and 1 pickle spear. Normally I add pickle brine to my tuna salad to give the flavor some depth. But because I added the ceviche juice, there was plenty of liquid. Left out the avocado so I could eat another slice of bread. So delicious and now satisfied!!
    For the future, I think I’ll leave out the mayonnaise since I couldn’t taste it. 

  11. Tried this last night. It was amazing! Filling, low on points, and delicious. It’s definitely going to become one of my staples when I have avocados!

  12. what does the vinegar do?

  13. Do you know how many points without the bread?

  14. Gina i LOVE all your recipes 😀 Being from Venezuela i'm so glad that you have so many with that tropical, south american flavor. BTW i know you love avocados so it will be interesting if you make avocado mayonnaise

  15. I am a diabetic and would like to know if your recipes are diabetic friendly

  16. Instead of mayo or yogurt (dairy), I use a non diary product called veggenaise. It is usually made with soy and it is just delicious. It is not ff, so go lightly as you would with any mayo but it doesn't contain any animal products if one is staying away from dairy or lactose intolerant.

  17. Oh my gosh, this is Delicious! I am eating this right now (on a low carb wrap) and I am in absolute heaven! <3

  18. this came really good, its simple and cheap, and good protein source..

  19. How long will this last in the fridge?

  20. This came out delicious!!! I don't usually like carrots but added them anyway – the whole combination is so good! Thanks – I had been eating tuna all wrong…

  21. Probably tastes better with mayo than greek yogurt. I just made this with greek yogurt and it was very bland tasting. I added a bit of curry powder to the tuna mixture to give it some flavor. Was ok.

  22. Thanks for this recipe. It was yummy!

  23. Try this with multi grain sandwish thins less calories

  24. Yum! Great lunch idea! 🙂

  25. I love when i make something and it looks just like the picture.

  26. Wow, will try this, but what is a good substitute for the mayo or yogurt…no dairy

  27. This was absolutely awesome. Even my kids liked it. And they hate everything. However, I did substitute sweet pea shoots for the alfalfa sprouts as they are not sold in our stores due to the bacteria danger. Also, I substituted non-fat miracle whip and used safeways's Mountain Grain bread. With these substitutions, my calorie count came down to 198 calories!

  28. There has been a recommendation to not eat sprouts- risk of bacterial contamination is too high.

  29. Really loved this! I never thought of putting carrots in tuna salad. It looksmgreat on a plate and tastes even better. Thank you.

  30. Definitely making this again because it tastes delicious! Thank you

  31. Lovely recipe! I'm going to make this today, for my birthday party. I hope the guests will like it:)

  35. This looks so yummy! I love avocados too 🙂 I've never made tuna with diced carrots or Greek yogurt (instead of mayo) but I think I might try it. Thanks for sharing!!

  36. This looks so healthy and delicious! I love a good tuna sandwich 🙂

  37. This is so beautiful! I'm going to feature it on my next "Wonderful Wednesday" post on Ducks 'n a Row. My readers will LOVE it!:)

  38. The boyfriend LOVES tuna but I can't eat it after I became ill years ago (bad mayo but it ruined the taste for me). Think I will make this as a chicken salad instead.

  39. Sounds delish! Perfect lunch!!

  40. It looks so delicious , I'll try this today : thanks Gina for all your recipes.

    I hope for you and all your family the Best for this New Year.

  41. If you haven't tried water chestnuts in your tuna salad it is fabulous!!! I love the crunch it gives it. I can't wait to try this!

    • Try a little jicama chopped into small sticks!! I like them better the water chestnuts and they are not as starchy.

  42. this will definitely be added into my lunch rotation

  43. Looks and sounds delicious. When I was a teenager, my Dad and step mother would take me to a cafe that served tuna with shredded carrots, onions and sprouts on mutligrain bread. I've been replicating myself for years on whole wheat pita. I love avocado and have never thought of pairing a veggie tuna sandwich and avocado. It was delicious. Thanks for the wonderful lunch idea.

  44. This is my kind of lunch! I adore tuna (though am the only one in my house) and avocados seem like the perfect partner in crime.

  45. I love all of your recipes and can't wait to try this one and get your cookbook once it comes out!

  46. I love adding avocado to pretty much everything! Healthy fat + fiber = happy Katie 🙂

  47. Oh! That looks tasty and bet it would be good without the bread as a lettuce wrap.

  48. Totally agree with you about avocados – just love em! This sandwich looks so tasty I'm adding tuna to my grocery list now!

  49. Gina, where have you been able to buy sprouts?? We can't even get them at Jimmy Johns anymore here in Columbus because of the salmonella scare!

  50. I love each and every ingredient in this sandwich. So delicious and healthy. thanks for sharing the idea of pulsing other veggies along with it 🙂

  51. No lie, I just made a tuna+rice+avocado salad before reading this. It's a great gf alternative to sandwiches. Mish-mash 1 c dry brown rice, cooked; 1/2 avocado, mashed, 1 can tuna, 2 T lemon juice, dashes of paprika, pepper, cayenne, garlic powder to taste together in a bowl. It's helping me through the flu!

  52. If it's got avocados count me it! This sounds so yummy.

  53. Is this on regular bread or lite bread? Just wondering for the points values. Looks delicious!

  54. Just bought a couple of avocados and tomatoes! This is perfect. Thank you!

  55. Avocados and tuna sandwiches two of my favorites!

  56. What a nice new way to enjoy a tuna sandwich!

  57. this looks so delicious! can't wait to try!

  58. How much celery, onion, and carrot is it before it's minced?

  59. having this today for lunch!
