Caponata is a Sicilian dish with eggplant, zucchini, tomato, and peppers traditionally cooked in oil and vinegar and flavored with sugar, raisins, capers, olives, and pine nuts. It's tangy, sweet, crunchy, and salty all at the same time. Serve at room temperature as a side dish to grilled fish or as a starter on toasted bread. Store leftovers in fridge and reheat gently. It will taste even better the next day!
