I originally got this recipe from my Great Grandma Ce. But I came up with the layered idea. Originally there were no corn tortillas, and it was more like a sort of meat loaf pie. This recipe is interesting, very tasty, and kid-friendly too!
Heat oil in large skillet and add onions; cook until tender, but not brown.
Add beef, brown well and Drain.
Mix in the Taco Seasoning and 3/4 Cup water; let simmer for 5 minutes, uncovered, stirring frequently, until spice mixture is no longer runny.
Stir crushed tomatoes, corn, and cornmeal into the meat; mix well.
In an 9X9 round pyrex (or well greased metal) baking dish, place 4 of the 8 tortillas on the bottom, spread out, to cover the pan, add 1/2 of the meat mixture over the tortillas,and then 1/2 of the cheese.
Repeat this layering process, ending in cheese.
Place in oven to heat through, and melt cheese (about 25 minutes).
