Caponata is a traditional Sicilian dish that is perfect for vegetarians. It is made with eggplant, tomatoes, onions, celery, capers, olives, and vinegar. The vegetables are sautéed until tender and then simmered in a sweet and sour sauce. The result is a flavorful and tangy dish that is perfect as an appetizer or a side dish. Serve it with crusty bread or as a topping for bruschetta. This dish is a great way to showcase the flavors of the Mediterranean.
