My family pulled together recently during a crisis. At any one time there were 6 - 7 adults to feed. I took the first couple of days and my sister took some and together we managed quite well. This recipe is one that she made and it was really REALLY good. So I took it home and made sure I could duplicate it with similar results (or in this case, my husband could duplicate it). And now it's in MY cookbook!
Brown the ground beef with the onion. Add the peppers, taco seasoning, dressing, beans, and tomatoes.
Spray a 9" x 13" pan with non-stick cooking spray. Layer 2 tortillas in the bottom and 1/3 of the meat mix. Dot with some sour cream and cheese. Repeat layers twice more. Top with last 2 tortillas and some cheese.
