Preheat oven to 350 degrees.
Heat oil in a large skillet.
Add onions and cumin seeds. Then, add green chiles, beef, salt and pepper. Cook thoroughly.
Add the beans and remove from heat.
Assemble the enchiladas using an assembly line of: tortilla, one spoonful of enchilada sauce, one scoop of beef mixture, one handful of cheese. Roll it up burrito style and place it snugly in a glass casserole pan. Repeat until beef mixture is gone.
Pour leftover enchilada sauce over the top, along with any extra cheese.
Bake uncovered for 20 minutes, or until the cheese is melted and tortillas are slightly crispy.
