Grease bottom of 9x11 baking dish. In medium skillet, brown ground beef with onions & drain grease. Stir in refried beans and 1 can of enchilada sauce. Heat mixture until warm.
Spoon 3-4 Tablespoons beef mixture onto burrito tortilla. Sprinkle with some cheese. (Reserve 6 ounces cheese for top). Fold tortilla around mixture, starting at bottom and bring sides in and fold down top to close. Place in baking dish. (I pour a little of the 2nd can of enchilada sauce on the bottom before I place them in the dish). Repeat w/remaining mixture.
After they are in the dish, pour remaining can of enchilada sauce over all & sprinkle with reserved cheese. You can add more cheese to your taste. Taste great with lot’s of cheese on top.
