Pinto beans are an amazing source of protein. They can be used to make a great bean dip, added to salads, soups, stews and make an amazing Mexican bean and veggie medley for tacos and nachos. To prepare, rinse the beans and then soak for 6-8 hours. Follow by boiling the beans in freshwater (three times more water to beans) for 1-2 hours until soft and tender.
