Black beans are a delicious and frugal way to add more protein to your family's diet. They require very little effort to make just a little planing ahead. As a child I rarely would eat black beans, I was a pinto bean girl and nothing was going to change that. Then a few summers ago I spent three weeks living with a family in La Antigua, Guatemala going to Spanish language school. Refried black beans were a frequent part of our meals. Never once was their a pinto beans in sight. To my surprise I loved them! Since then I have been cooking with more black than pinto beans. When talking to some of my girls I discovered that the pinto beans and flour tortillas we all consider as staples of Mexican food are more of a northern Mexico thing. In southern Mexico corn tortillas and black beans are staples in the locals' diets.
