Sliced Tropea red onions in oil are a delightful and flavorful preparation of one of Italy's most prized onion varieties, the Tropea onion, known for its sweet, mild taste and vibrant red color. The onions are carefully sliced into thin rings and preserved in high-quality olive oil, which enhances their natural sweetness and adds richness to their flavor. The oil infuses the onions with a subtle, savory depth, making them perfect for a variety of dishes such as salads, antipasti, sandwiches, or as a topping for meats, pizzas, or grilled vegetables. The combination of the tender texture and the aromatic oil makes for a deliciously versatile ingredient.
