Panzanella salad is a traditional Tuscan salad that is perfect for summer. It is made with stale bread, tomatoes, cucumbers, red onions, and basil. The bread is soaked in water and then squeezed to remove the excess liquid. It is then torn into bite-sized pieces and mixed with the other ingredients. The salad is dressed with olive oil, vinegar, salt, and pepper. Panzanella salad is a great way to use up leftover bread and it is a refreshing and flavorful dish. It is often served as a starter or a side dish in Florence.
