Enchilada Casserole

This is a great dish to make and bring to friends and family who have just had babies.  I received this after my last one and I just made it to day to bring to a friends house!  Here are the ingredients:

1lb ground beef
1 chopped onion
2 cloves garlic, minced
1 can rinsed and drained black beans
4tsp chili powder
1/2 tsp salt and pepper
1c water
16 oz can corn
16 oz jar taco sauce
1c sour cream
16oz shredded cheese
whole wheat tortillas

Brown the ground beef, then add the chopped onion and garlic and saute until soft.  Once soft, add the black beans, chili powder, salt, pepper, and water.  Bring to a boil and simmer for 10 minutes.  In a 9X13 casserole pan, spread 1/3 of the taco sauce on the bottom and cover with tortillas.  Add 1/3 sauce on top, then add the beef mixture, sour cream, corn, 1/2 of the cheese and top with another layer of tortillas.  Top with the rest of the sauce and cheese and bake at 350 for 45 minutes.
