Yum...gonna try this soon. I can see doing variations of this with other meats, sauces, etc., too.
I have not made this version of the tortilla pie, but did invent my own.
I used flour tortillas, the hamburger meat, corn,beans, onion slices, the green chili slices, cheese, just kept making layers, and I think I might have dumped a can of either mushroom soup or diced tomatoes over the layers as I went, knowing me it was both.
Baked it an hour or so at 350 degrees.
My brother came to visit and he liked it, what was left, I froze for instant meals.
