Heat the oven to 400.
On medium heat, brown the meat with onions; drain. Drain the beans.
Stir in the salsa and beans into the meat mixture.
Wrap the 12 tortillas in a wet paper towel and microwave for 2 minutes until hot and soft.
Spray the bottom of a 9×13 pan. Lay 4 tortillas on the bottom of the pan (they will be
overlapping).
Cover with the meat mixture, sprinkle with cheese. Layer with 4 more tortillas.
Spread 1/3 of the sour cream over the tortillas and repeat the method above (tortillas, sour cream,
meat mixture, cheese), ending with cheese on the very top.
Cover with foil. Bake for 35-40 minutes or until casserole is heated through.
Let stand 5 minutes before serving. Garnish with shredded lettuce, tomatoes, and cilantro. Serve
with Tabasco sauce.
