Chiffonade of fresh basil, seeded cucumber and flaked Parmesan or feta cheese are all common additions to this summery salad. The proportions of this bread and tomato salad are flexible; adjust them to your liking or based on what you have on hand. We used a prepared vinaigrette in this updated version of the classic dish, but you can replace it with a combination of olive oil and balsamic vinegar, if preferred.
