Variety of bean is a term used to describe the many different types of beans that are available. Two of the most common varieties are Haricot, which has seven letters, and Fava, which has four letters. Haricot beans are small, white, kidney-shaped beans that are commonly used in soups and stews. Fava beans are large, flat beans that have a nutty flavor and are often used in Mediterranean dishes. Both types of beans are high in protein and fiber, making them a healthy addition to any diet.
