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.
Why This Salad Is My Family’s Favorite Way to Use Tomatoes
It’s not an exaggeration to say we make this multiple times every summer, especially when we get lots of tomatoes from the garden. Here’s why I love it.
- Simple: When you start with beautiful sun-ripened tomatoes, you don’t need to add a lot of other ingredients to make a delicious salad. And that means this recipe is incredibly easy, too.
- Versatile: Scale up the recipe for a party, toss it with orzo for an easy pasta salad, spoon it onto toasted slices of bread for bruschetta, or come up with your own way of serving it.
- Light and summery: When it’s hot outside, I rarely feel like big, heavy meals. I like that this salad is fresh and light!
