Preheat oven to 350 F. In a small bowl, combine stuffing ingredients. Place chicken in a heavy freezer wrap bag. Pound breasts until about 1/4″ thickness.
Mound stuffing on flattened breasts & fold over, tucking in ends. Place a small amount of stuffing on bottom of baking dish & lay breasts on top. Any extra stuffing can be placed around & on top of chicken as well.
Cover with foil & bake 15 minutes. Remove foil & continue to bake another 15 minutes or until chicken tests done.
