Oven Tacos

2 lbs ground beef
1 small onion diced
1 small can diced green chilies
1 package taco seasoning
1 (8 ounce) can tomato sauce
1 (16 ounce) can fat free refried beans
2 cups shredded Colby-jack cheese
18-20 hard taco shells

Optional Condiments-
Lettuce (shredded)
Tomato (diced)
Salsa
Guacamole
Sour Cream
Olives, sliced

1. Preheat the oven to 400 degrees.

2. 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.

3. 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.

4. Remove from the oven and top with any optional condiments for serving.
