Fall Apart Crockpot Chicken

This is from Hillbilly Housewife. Sounds a little weird, but it seems that some of the weirdest combinations make the most delicious food. We had it over rice, and it was tasty.

3-4 boneless, skinless chicken breasts
1 stick butter
1 pkg. dry Italian salad dressing mix

Cook on low in crock pot for 3-4 hours. Shred chicken. Then add:
1 8 oz. pkg. cream cheese
1 can cream of chicken soup
1/2-1 can of water (measure in the soup can)
Heat through; about an hour. Serve over noodles, rice, whatever you like.
