Panzanella is a refreshing and vibrant Italian salad that is perfect for summer. It's made with stale bread, tomatoes, cucumbers, red onions, and fresh basil. The bread is soaked in water or vinegar to soften it, then combined with the chopped vegetables. A simple dressing made from olive oil, vinegar, salt, and pepper is drizzled over the salad to enhance the flavors. Panzanella is a great way to use up leftover bread and enjoy the abundance of summer produce. It's a light and satisfying dish that can be served as a side or a main course for a light lunch or dinner.
