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