Blend the softened butter with parsley, chives, pepper, and salt. Divide into 4 portions and chill until firm.
Flatten each chicken breast half to about 1/4-inch thickness by pounding each
in a one gallon freezer bag. Place a portion of the chilled butter
mixture in the center of each flattened chicken breast half. Roll each to
completely enclose the butter. Dust each roll in flour then dip in beaten egg
and water. Roll in bread crumbs then place in lightly greased baking dish.
Cover and bake at 350° oven for 45 minutes. Uncover and bake 15 minutes
longer.
