Want a good side dish for almost any Tex-Mex meal? Refried beans are about as good as it gets. Traditionally, these are made with lard and pinto beans, but there’s no rule. After all, you can mash up or puree almost any bean and it will probably be delicious. For this version, I like to use butter and black beans for a nice twist on the classic. Try these in a burrito or taco. Or just eat them with a spoon!
