1/2 c. chopped onion
2 tbsp. shortening
1 tbsp. flour
1/2 c. milk
1 (4 oz.) can green chili peppers, drained and chopped (1/3 cup)
1/2 tsp. salt
2 c. diced cooked beef (I use hamburger meat)
2 med. tomatoes (peeled and chopped) I use 2/3 can Rotel
8 corn tortillas
1/4 c. oil
1 c. shredded cheese (Cheddar)

In skillet cook onion in shortening until tender but not brown. Blend in flour. Add milk, chili peppers and salt. Cook, stirring constantly, until thick and bubbly. Stir in beef that has been browned with seasonings and tomatoes, heat through. Keep warm. In small skillet heat tortillas (one at a time) in hot oil until limp (about 15 seconds per side). Place a hot tortilla in baking pan, top with beef mixture and a small amount of cheese (2 to a stack). Bake at 350 degrees for 20 minutes. When cooking meat, I add cumin, garlic, salt and pepper.
