Panzanella is a refreshing Tuscan salad made with stale bread, tomatoes, cucumbers, onions, basil, and olive oil. The bread is soaked in water to soften it, and then combined with the fresh vegetables and herbs. A simple dressing made with olive oil, vinegar, salt, and pepper is drizzled over the salad to enhance the flavors. Panzanella is a light and summery dish that is perfect for using up leftover bread and showcasing the vibrant flavors of Tuscan produce.
