Melt margarine in a saucepan. Saute onions and beef. Cook until beef is no longer red. Add chili powder, salt, pepper and cumin. Continue to cook until beef mixture becomes very dry. Using a slotted spoon, remove beef from pan and transfer to a bowl. Stir in half of grated cheese and half of sour cream. Mix well and set aside. Using the same pan with its oils, saute bell peppers. When softened, add tomato sauce and spices. Season with hot sauce. Allow to boil. Remove from heat.

      Divide beef mixture evenly between 12 pieces of tortilla. Place meat on the center of the tortilla and roll to secure filling. Arrange tortilla rolls side by side on a baking dish. Set aside. Pour tomato sauce over enchiladas and top with the other half of sour cream and grated cheese. Bake in a pre-heated 350 F oven for 25 to 30 minutes.
