Georgian Tomato and Cucumber Salad with Walnuts

In Georgia (the country, not the state), walnuts aren’t in salad dressing, they are the salad dressing. Crushed and tossed with tomatoes and cucumbers, the nuts create a creamy-savory dressing that adds as much texture as flavor. We learned this version in Georgia from wine horticulturist Giorgi Barisashvili. We salt the tomatoes and cucumbers to enhance their flavor and draw out excess moisture, and we toss slices of red onion in vinegar to soften their bite. Campari tomatoes (sometimes called cocktail tomatoes) are a good choice in the off seasons.
