I dont like the store bought red enchilada sauce, so I make my own. You can use any beans you like, black, pinto, chili or kidney. I have also left the beans out, and spread the tortilla with refried beans before adding the beef mixture. Either way is great. I like to make the sauce and beef mixture the night before, then all I have to do is assemble and bake, and its super easy. This recipe freezes well. Sometimes I like to make a double batch of the sauce, and freeze for later use.
