Soup beans are a type of legume, often used in soups and stews. The two most common types of soup beans are LENTILS and limas. LENTILS are small, lens-shaped legumes that come in a variety of colors, including brown, green, and red. Limas, also known as butter beans, are larger, flat, oval-shaped legumes that are usually green or yellow in color. Both LENTILS and limas are high in protein and fiber, making them a nutritious addition to any meal.
