The term 'BEAN-SPROUTS BEAN' can be solved by the four letter word 'MUNG'. Mung beans are a type of small, green legume that are native to India and have been cultivated for centuries. They are often used in Asian cuisine, particularly in stir-fries and soups. Bean sprouts are made from mung beans and are a popular ingredient in many dishes. They are high in protein and fiber and low in fat, making them a healthy addition to any meal.
