Scallions, also known as green onions, are a type of Allium vegetable related to onions, garlic, and leeks. They are a popular ingredient in Asian cuisine and are often used in stir-fries, soups, and salads.
 
Scallions are slender, green, and white onions with a mild flavor. They are typically harvested when they are still young, before they develop a bulb, and have a long white stem that is topped with green leaves. The entire plant is edible and can be used raw or cooked.
