1 lb lean ground beef
1 onion, chopped
2 1/2 cups salsa

2 Tablespoons Taco Seasoning
1/4 teaspoon Cumin

Directions
Preheat oven to 400 degrees. In a large skillet, cook the ground beef and onion over medium-high heat until meat is no longer pink. Drain fat. Stir in salsa, beans, cheese whiz, sour cream, taco seasoning and cumin. Stir well and cook for 5 minutes. Remove from heat. Spray a 9x9 inch baking dish with cooking spray. Spoon a 1/3 of meat mixture in the bottom. Sprinkle with 1/2 cup of cheese. Layer 3 flour tortillas over the top. ( you will have to cut one of the tortillas so they fit ) Spoon another 1/3 of meat mixture on top of the tortillas, then sprinkle another 1/2 cup of cheese. Do one more tortilla layer, the last of the meat mixture and sprinkle the rest of the cheese on top. Bake for 25 minutes or until cheese has melted and it's hot and bubbly. Let stand 5 minutes or so before slicing. Makes 9 servings.
