Mexican Lasagna

A great make-ahead meal to place in the freezer.

Ingredients

2 lbs ground hamburger	1 cup medium heat taco sauce or 1 can (14 oz) fire roasted tomatoes
2T chili powder	1 can corn, drained (or frozen)
2 tsp ground cumin	tortillas
1/2 an onion, chopped	2 1/2 cup shredded cheese (cheddar, marble jack, pepper jack all work well)
1 can (15 oz) black beans, drained

Directions
Preheat oven to 425º F.

Preheat a large sauce pan/skillet over medium high heat. Add hamburger, chili powder, cumin, onion and oil if necessary. Brown the meat, 5 minutes. Add taco sauce or fire roasted tomatoes, black beans, and corn. Heat the mixture through and salt to taste.

In 2 casserole dish (i normally do 1 big and 1 small) place a small layer of meat mixture on the bottom, just enough from keeping the tortillas from sticking. Build your layers with meat mixture, tortillas then cheese. Repeat: meat, tortilla, cheese again.

Place one of the dishes in the freezer for later use. Bake other pan for 12 - 15 mintues or until cheese is brown and bubbly. Serve with sour cream.
