How about adding some beans to your plate?  Your plate should be half of fruits and vegetables.  Beans, such as black beans, pinto beans or kidney beans are the perfect choice because they are high in fiber which keeps you full longer and are loaded with protein.  A half cup serving of beans provides 6 – 7 grams of dietary fiber as well as many essential minerals including iron, phophorus, magnesium, potassium, zinc and calcium.
