Panzanella is a classic Italian salad that originated in Tuscany but is also popular in Sicily. It is 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 other ingredients. The salad is dressed with olive oil, vinegar, salt, and pepper. Panzanella is a great way to use up leftover bread and is a delicious and satisfying salad option.
