Legumes are plants that bear fruit in the form of pods enclosing the fleshy seeds we know as beans. Peas are one of the few members of the legume family that are commonly sold and cooked as fresh vegetables. Other members of the legume family, including lentils, chickpeas, and beans of all colors are most often sold in dried form.
