Stacia's Chicken Enchiladas

1. Either saute or boil, then chop: 4 chicken breasts.
2. mix together:
     1 can tomatoes with green chilies
     1 can cream of chicken soup
     1 can cream of celery soup
     1 small can enchilada sauce
     1/2 onion, chopped
     1 lb grated cheddar cheese (reserve some to sprinkle on top)
3. Add chipped chicken to half of sauce. Roll in flour tortillas. Put in large baking pan. Cover with remaining sauce, sprinkle with cheese (I did this when it had about 5 minutes left in oven).
4. Bake at 350 degrees for about 30 minutes.
