Where would cooking be without the distinctive smell and taste of onions? With a range of sizes, colors (green, yellows, whites and reds) and flavors, onions spice up any dish. Whether sautéed, fried, eaten raw or cooked in soups and sauces, onions are a necessary part of most recipes. Onions are easy to grow and rich in flavonoids and many other nutrients, meaning they’re as healthy as they are tasty.
