Panzanella is Italian bread salad made with fresh chopped tomatoes and day old toasted or stale bread. Many traditional Tuscan recipes start with soaking the bread in water and then ringing it out. They are then tossed with the tomatoes and dressing (always made with extra-virgin olive oil and often garlic.)  A lot of Americanized versions of the recipe (including this one) don't include soaking the bread and wringing it out. I never thought that made much sense, since there is so much moisture from the tomatoes!
