This is Mark's favorite casserole:
1 chopped onion
1 chopped green bell pepper
14 oz canned tomatoes
3/4 c salsa
1 T garlic
2 T cumin
2 15 oz cans of black beans, drained
1 c corn or more. The more the better
8 corn tortillas
1.5 c shredded cheese
In a LARGE skillet, over medium heat, combine first 6 ingredients, bring to a boil. Reduce heat and simmer uncovered for 5 minutes. Stir in beans.
Spread 1/3 of the mix over bottom of 13x9" pan. Top with 1/2 the tortillas, 1/2 c cheese, 1/3 of the mix, remaining tortillas, 1/2 c cheese, last 1/3 of the mix. Cover with aluminum foil and bake for 30 minutes in 350 degrees F. Sprinkle remaining cheese and wait for 10 minutes or so before serving.
** I don't follow these directions very closely, that's why I ended up topping it with some more tortillas. There's also tortillas at the bottom! Either way, it's yummy!
