Panzanella is a refreshing Tuscan salad made with stale bread, tomatoes, cucumbers, onions, basil, and olive oil. The bread is soaked in water and then squeezed dry before being combined with the other ingredients. The salad is dressed with olive oil and vinegar, which helps to soften the bread and infuse it with flavor. Panzanella is a perfect dish for summer, as it is light, flavorful, and utilizes fresh seasonal ingredients.
