Heirloom Tomato Salad is the perfect easy summer side dish. While the juicy, ripe tomatoes are the star, red onion, briny olives and fresh basil add lots of flavor too.

Summery Heirloom Tomato Salad Recipe
It’s hard to resist colorful heirloom tomatoes when I see them at the farmers’ market, but sometimes I buy so many, I don’t know what to do with them all. This heirloom tomato salad solves that problem in a delicious way. A simple summer tomato salad made with Kalamata olives, red onion, extra virgin olive oil, and garden fresh basil, it’s my husband’s recipe and it’s become my favorite ways to eat tomatoes. We serve this as a side dish or for lunch with a nice crusty bread like my homemade Sourdough Bread.

Tomato Salad Variations
Here are a few more ways to make this heirloom tomato salad.
- Try different herbs: Almost any herb pairs well with tomatoes. Try fresh oregano, parsley, or dill, or a combination of herbs from your garden.
- Add cheese: Shaved Parmesan or sliced fresh mozzarella layered with the tomatoes would be delicious.
- Swap the olives for capers: They have a flavor that’s bright and briny at the same time.

Proper Storage
Refrigerate heirloom tomato salad in an airtight container for up to 3 days. I like to let it come to room temperature before serving.

I love this and I'm not a big tomato person.
