Cook ground beef then mix with enchilada sauce. Then create how many layers you want of ground beef, sliced cheese and tortillas. Cover with a thin layer of enchilada sauce or salsa and a sprinkling of cheese and bake.
For extra credit sauté some diced onions and bell peppers in the pan before browning the ground beef.
Well, I wouldn’t call it lasagna, but I’ve been making my enchiladas casserole style for decades- rolling them is just way too much of a pain.
I’d never use salsa- too wet. I prefer Las Palmas sauce, cooked down just a bit; it’s too watery out of the can. Try boiled shredded chicken breast for a nice flavor. Also green onions and black olives
