Enchilada Casserole

It has been a crazy week!! This was made a week ago and I'm now just getting around to posting it. Luckily, I'm finally getting caught up around the house and things and more delicious recipes will be posted tonight or tomorrow! So stay tuned! This recipe came from Kraft Foods. Instead of using raw meat, I just used some I had previously browned up and had in the freezer. If you do that, do just like you would in the recipe, just not for as long, because you don't need to cook the meat. Enjoy!
1 lb. ground beef
1/4 cup chopped onions
1 can (8 oz.) tomato sauce
1/2 cup water
2 tsp. chili powder
4 corn tortillas
1 cup shredded Cheddar Cheese
1/2 cup chopped tomatoes
1/4 cup sour Cream
Microwave meat and onions in 2-qt. microwaveable dish on high 4 to 6 min. or until meat is no longer pink, stirring every 2 min.; drain.

Stir in tomato sauce, water and chili powder. Microwave 5 to 9 min. or until slightly thickened, stirring every 4 min.

Transfer to bowl. Place 1 tortilla in same microwaveable dish; top with layers of 1/4 each meat sauce and cheese. Repeat layers 3 times.

Microwave 2 to 5 min. or until heated through. Let stand 5 min. Top with tomatoes and sour cream.
