*While Navy beans are the more traditional choice, I used pinto beans because I always have them on hand. They have a great creamy texture and earthy flavor. You can use either type of canned beans in this recipe.**Worcestershire sauce enhances the umami flavor of the sauce. You can sub soy sauce for Worcestershire or omit it altogether if you are veggie/vegan.***Apple cider vinegar adds a nice tanginess to the sauce. White vinegar also works well.
