In my recipe, pinto beans and kidney beans are simply fried up with onions, garlic and spices, then lightly mashed. While I am sticking to a vegetarian version of the dish, many recipes only require pinto beans and some include bacon.
For convenience and to save time, I use canned beans. If you can't find Pinto Beans, you can substitute them with black eye'd beans. You may also notice the name is misleading as the beans are simply fried once.
