Cream Cheese Chicken (crockpot)

(from Dinner's On Me!)

4-6 chicken breasts (boneless, skinless)
1/2 cup butter or margarine
1 package dry Italian dressing mix
1 can cream of chicken soup
8 oz cream cheese, cubed
1/2 cup milk

Place chicken breasts, butter & Italian dressing in crock pot on low. Cook about 6 hours. One hour before serving, add the final 3 ingredients. Cook all ingredients until they are melted and it is the consistency of gravy. Use two forks to shred the chicken. Serve over rice, mashed potatoes, or pasta.
