Preheat the oven to 400 degrees. 

In a large skillet brown ground beef and onion over medium-high heat. Drain off any excess liquid. Return to pan, add chilies, refried beans, tomato sauce, and taco seasoning. Mix well and cook for a few minutes if mixture seems runny.

Spoon the taco meat mixture into the taco shells and place into a 9 x 13 inch baking dish, standing up. Sprinkle cheese over the top of the taco meat in each shell. Place into the oven and bake at 400 degrees for 10-12 minutes or until the cheese has melted and the tacos are heated through.
