HEAT oven to 375F. Pour sauce into 13x9-inch baking dish. Stir in 1/4 cup (4 Tbsp.) Parmesan. Add chicken; turn to coat both sides with sauce. Cover with foil.
BAKE 30 min. Uncover.
TOP with remaining cheeses; bake 5 min. or until chicken is done (165F) and cheese is melted.
Message: With a little help from a grown-up, this chicken parm dish will be all gone before you can say, "Holla!"
