Mung bean noodles are a popular noodle used in a variety of Asian dishes. Mung bean noodles are also called crystal or glass noodles because they become very transparent when cooked. They are most commonly used in Chinese cuisine, stir-fried with vegetables and meat dishes, and in soups. In India, they are eaten with ice cream, but in Thailand, they are popular in spicy and sour seafood salads.
