Panzanella is a salad consisting of toasted cubes of bread tossed with vegetables and vinaigrette. The salad is then marinated for at least one hour. The bread should be very firm so that it will endure the soaking of dressing. Vegetables can include tomatoes, peppers, cucumbers, and onions. Lots of garlic, capers, black olives, and anchovies are added to the salad.
