Combine cream cheese, margarine, salt and pepper.  Stir in chicken pieces and mushrooms.   Separate rolls.  Spread on each roll 2 – 4 Tb. of the chicken mixture.

Roll from the tip end first, tuck under sides.  Seal.  Roll each in melted butter then in bread crumbs.  Put into bag and freeze. 

When thawed, bake uncovered at 350 on an ungreased cookie sheet for approx. 20 minutes or until golden brown.  Serve with gravy if desired.
