Together, they balance one another beautifully, creating a refreshing yet satisfying salad that’s bright with flavor.

Anyone can prepare it in under ten minutes and enjoy it hours later, chilled and bursting with flavor. It’s this unfussy nature that makes it a go-to recipe for busy home cooks, health-conscious eaters, and anyone who appreciates fresh, uncomplicated meals.
