|Brown hamburger and drain, if necessary. Add onions to hamburger and sauté till onions are clear. Stir in Fajita Seasoning and remove from heat.
Mix together enchilada sauce and soups.
Spray 13"x9" pan with Cooking Spray. Layer 4-6 tortillas on the bottom of the pan, tearing the tortillas in half if necessary. Spread half the hamburger over tortillas. Spread half the cheese over the hambuger.
Layer 4-6 more tortillas, the remaining hamburger, and the remaining cheese (reserve about ¼ cup for the top if you wish.)
Layer the remaining tortillas on top, and pour the remaining sauce over all. Make sure it covers all the tortillas (any exposed will burn or get crusty.) Sprinkle the last of the cheese on the sauce. Cover and bake 40-60 minutes in 350 degree oven. (Or long enough for it to get heated through.)
Use flour tortillas instead of corn tortillas.
Use 2 cans of tomato soup instead of 1 can tomato & 1 can mushroom.
Add your favorite items to the hamburger, such as green pepper, green chilies, mushrooms, cilantro, etc.
If you want to get fancy, you can roll individual enchiladas instead of just layering it. First soften the tortillas by either quick-frying them in hot oil or heating in the microwave for 20-30 seconds each. Put a spoonful of hamburger on tortilla. Top with spoonful of shredded cheese. Roll tortilla up and put seam side down in the pan. Continue with remaining tortillas. Spread any remaining hamburger and cheese over tortillas, and top with the sauce.
Dare I say it: any taco seasoning will work instead of the Watkins Fajita Seasoning. (But it won't be as good, so there.)
This keeps well in the fridge prior to baking and is great as leftovers.
Serve with your favorite salsa or taco sauce.
Serve with refried beans, Spanish rice, and/or a salad.
