1) Preheat oven to 375 degrees F.

2) Place chicken breast between two sheets of cling wrap. Pound chicken evenly all over until about 1/4 inch thick.

3) Mix cream cheese, spinach, garlic salt,1 cup mozzarella and 3 Tablespoons of Parmesan until well blended; spread onto chicken breasts. Starting at one short end of each breast, roll up chicken tightly. Secure with wooden toothpicks, if desired. Set aside.

4) Beat egg in a shallow dish. Mix remaining Parmesan and bread crumbs in a separate shallow dish. Dip chicken bundles in egg, then roll in crumb mixture. Place, seam-sides down, in 13×9-inch baking dish sprayed with cooking spray.

5) Bake 30-35 minutes. Remove and discard toothpicks, if using. Serve topped with pasta sauce and remaining mozzarella.
