Panzanella is a classic Tuscan bread salad. It is made with stale bread, tomatoes, cucumbers, onions, basil, and olive oil. The bread is soaked in water or vinegar to soften it, then it is tossed with the vegetables and dressed with olive oil and vinegar. Panzanella is a refreshing and light dish, perfect for the summer months. It is a great way to use up leftover bread and is a staple in Tuscan cuisine.
