More similar, quick and easy lunch ideas I love are Tuna Deviled Eggs and Spicy Crab Stuffed Avocado. These are great recipes for bread-less, gluten free or low carb alternatives.

I often think up recipe ideas that sound good in my head but may not always translate into a blog-worthy recipe. These tuna topped tomatoes are one of those ideas I wasn’t sure how it would turn out. My first attempt I baked the tomatoes, so they were soft and warm but they were pretty messy to eat. Then I thought, why not just broil them. The result came out perfect, the tomatoes were nice and firm and plus this only takes 5 minutes to make! Great for gluten-free and low-carb diets.

Hope you enjoy this recipe!

  1. Very tasty! I doubled the recipe, and halved the mayo since I used tuna in olive oil (drained 1 can, used the oil from the other). Quick and easy summer lunch!

  2. I made this today for lunch using fresh tomatoes from our garden. This was really good. I did not have cheddar cheese on hand so I used thin slices of Pepper Jack cheese and it was probably just as good as the cheddar cheese would have been.

    Absolutely delicious! Used 3 Roma tomatoes instead. Slightly salt & peppered the tomatoes then broiled alone for 2 minutes before adding tuna salad & cheese. Then broiled again for 4 minutes. Would also be delicious with avocado halves. Thanks for the recipe!

  4. i made this but subbed out red bell peppers for the tomatoes. it was so delicious and the peppers made it a little easier to eat because they held together! thanks for the recipe!

  5. Perfect lunchtime meal. I lacked onions and celery, so I subbed grated carrots and minced cucumbers, but it still came out great I ate the Tuna Melt with 1/2 an avocado and a salad. Yum! Yum. Thank you for the great recipe.

  6. I wonder if you could  scoop out the inside of the tomato and stuff the tomato with the tuna and top with cheese? When I made it two tomatos where to much maybe I got the wrong size tomatos.

  7. Could you use Greek yogurt instead of mayo? I don’t cook with it much but use it for cold tuna. 🙂

  8. This one surprised me how much I liked it! I had a few tomatoes I needed to use up and I did end up tweaking it a bit based on what I had. I added some capers to my tuna, used a little less mayo, scooped out the inside of the tomatoes, and just used shredded part-skim mozzarella (all I had)…so tasty and filling! Mine worked out to 4 smartpoints for all 4 halves! Thanks for such a great idea, I’ll be making this one again and again.
