Spray inside of crock pot with non-stick spray. Add in the stew meat, enchilada sauce, green chiles and beef bullion cubes. Cover with lid and turn on low heat. Cook for 8 to 9 hours.
After 8 or 9 hours, remove lid from crock pot and stir mixture together. The meat is ready, if it easily breaks apart. Using a slotted spoon, place 1/2 cup of meat mixture into the center of one tortilla. Roll up burrito-style and place into a 9×13 baking dish. Repeat with all tortillas.
Spoon the remaining sauce over the tops of burritos, and sprinkle with shredded cheddar cheese. Place under broiler in the oven, for 5 minutes or until cheese is melted and bubbly. Serve burritos with all your favorite toppings. (Salsa, sour cream, guacamole, etc) Enjoy!
