Sour Cream Enchiladas

This is a recipe my grandma gave me last week when I visited her. She said it was a recipe that froze well.

1 pound hamburger
1 package taco seasoning
1/4 cup water
1 can cream of mushroom soup
1 cup sour cream
1 soup can milk
10 tortillas (flour)
2 + cups of cheese

Cook hamburger then add the taco seasoning and water. Set it aside. Mix the cream of mushroom soup, sour cream, and milk. Cover a 9 x 13 pan with some of the soup mixture. Fill tortillas with meat and cheese and put them in the pan. Then pour the remaing soup mixture over the top. Cook at 350 degrees for 25-30 minutes.
