Full Belly beans are some of the most labor intensive crops we grow- harvesting each bean by hand can take hours. Green beans are an excellent source of both fiber and vitamin A, and also fuel human bodies with folates and iron. Fava Beans are an excellent source of protein, iron, copper, and fiber. Beans should be stored in the refrigerator, unwashed. Beans are available in the warm summer months of June, July, August, and September.
