Recipe shared by permission of Skyhorse Publishing. From the author: Lots of people have a favorite refried bean recipe, but I think my Dos Caminos version is special because we use avocado leaves and bacon, which adds a smoky flavor. They’re definitely better than what comes out of a can. When we were very young children, one of the first foods my parents ordered for my sister and me were black bean tacos in a small storefront Mexican restaurant in Denver, where we ate weekly. They are a simple, approachable food for any age.
