A caprese salad has always been one of my favorite appetizers. It's bright, fresh, and flavorful, and as long as tomatoes are in season, you'll find me munching away on it. The other night, however, as I was staring at my juicy red tomatoes, I had a thought. Without ruining the simplicity of the dish, was there a way to elevate it so it could become a hearty main, and not just a starter course?
