Namul is a type of Korean dish. It usually involves vegetables that have been steamed, lightly boiled, or marinated in a sauce or dressing. The vegetables used in namul can range from root vegetables like radishes, cucumbers, carrots, and potatoes to leafy vegetables like spinach, napa cabbage, and watercress. Some popular namul dishes also have meat, fish, egg, or other ingredients added to them for more flavor. Namul dishes can be eaten on their own, served as a side dish with a main course, used as an ingredient in a stir fry, or used as a topping to put on other dishes.
