Spray two 9 by 13-inch baking pans with a non-stick cooking spray. Preheat the oven to 375 degrees F.
In a skillet brown the ground beef over medium heat. Add the taco mix, follow the directions on the package to prepare.
Heat the refried beans in the microwave just until they are softened.
Fill each tortilla with the ground beef mix, refried beans, chilies, tomato, lettuce, and 1 1/4 cup cheese. Divide the ingredients evenly between the tortillas. Pour a small amount of the enchilada sauce over the ingredients in each tortilla.
Use around one teaspoon of sour cream on the rim of one side of the tortilla shell. Pull the opposite side of the shell to close the enchilada. Press the edge with the sour cream on top of the side that has been pulled over.
Cover pan tightly with aluminum foil. Place pan in the preheated oven and bake for 20 minutes. Remove from oven take off the aluminum foil. Sprinkle with remaining cheese and place back in the oven until cheese is melted about 2 to 3 minutes.
