Mexican Lasagna

I have tripled this recipe and frozen it in 9x9 pans.

1 pound ground beef
1 can mushrooms
1/4 tsp salt
1/4 tsp pepper
1 pkg Taco Seasoning
8 oz can Tomato Sauce
2 Tbsp Picante Sauce
8-10 Lasagna Noodles
2 Tbsp Onion
Tortilla Chips crushed

Cook lasagna noodles until done. Set aside and cook meat. Drain and add taco seasoning, oniond, salt, pepper, mushrooms, tomato sauce and picante. Grease 9x9 dish and layer noodles, meat, cheese and repeat. (If you want to freeze it, freeze at this point) When ready to eat, thaw and top with broken chips. Heat at 350 for 10-20 minutes until hot though and cheese is melted.
