Panzanella

Panzanella or panmolle ( Italian: [pamˈmɔlle]) is a Tuscan and Umbrian chopped salad of soaked stale bread, onions and tomatoes that is popular in the summer. It often includes cucumbers, sometimes basil and is dressed with olive oil and vinegar. It is also popular in other parts of central Italy. The 16th-century artist and poet Bronzino sings the praises of onions with oil and vinegar served with toast and, a page later, speaks of a salad of onions, purslane, and cucumbers. This is often interpreted as a description of panzanella.
