This tomato and onion salad is simple, quick, and makes the most of those fresh, juicy tomatoes. Pair them with thinly sliced red onion, fresh herbs from the garden, and a tangy homemade vinaigrette, and you’ve got a dish that tastes like pure summer.
It’s the kind of salad you’ll find at backyard barbecues and church potlucks—right next to other classics like healthy broccoli salad, easy frozen green pea salad or fresh green bean salad. And every time I make it, I’m reminded that the best food doesn’t have to be complicated.
