Onions are used in many cooking dishes, such as stews, soups, sauces, salads, and grilled dishes. They have a characteristic flavor, which can be sweet or spicy, depending on the variety and cooking time.
Onions are a good source of important nutrients, such as vitamin C, fiber, and several antioxidants.
