Put the stew meat into the crockpot. Put beef bouillon cubes on top and pour the enchilada sauce over the meat and cubes. Cook on low 6-8 hours or high 3-4. Cook until meat is very tender.
Assemble burritos by spooning refried beans and spreading them on the tortilla. With a slotted spoon, put about 1/2 cup of the meat mixture on top. Roll up like a burrito and place seam down in a 9x13 pan.
Pour remaining sauce from the crockpot on the top and sprinkle heavily with cheese.
Broil in the oven until cheese is melted and bubbly for about 5 minutes. Enjoy!
