Mix up the kinds of tomato you use in this juicy salad—and the window for flavorful varieties can be tight, depending on the weather. Using ultra-thin slices of prosciutto ham, crisped up in the oven, instead of bacon, is a fun twist and absolutely addicting. And add more texture by making rustic croutons to sprinkle on top: tear a small loaf of multi-grain bread into pieces, then sauté in olive oil (and more garlic) until golden and crunchy.
