I found this recipe while looking for something to use up some old ritz crackers. It turned out really good and definitely will be made again.
4 ounces Cream Cheese, softened
10 ounces fresh spinach, torn
1 1/4 cups Shredded Mozzarella Cheese, divided
6 tablespoons Grated Parmesan Cheese, divided
6 small boneless, skinless chicken breast halves, pounded to 1/4-inch thickness
10 RITZ Crackers, crushed
1 1/2 cups spaghetti sauce, heated
Heat oven to 375 degrees. Mix cream cheese, spinach, 1 cup mozzarella and 3 Tbsp. 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.
Beat egg in shallow dish. Mix remaining Parmesan and cracker crumbs in separate shallow dish. Dip chicken bundles in egg, then roll in crumb mixture. Place, seam-sides down, in 13x9-inch baking dish sprayed with cooking spray.
Bake 30 min. or until chicken is done (165 degrees). Remove and discard toothpicks, if using. Serve topped with spaghetti sauce and remaining mozzarella.
*To make ahead: Assemble chicken bundles and place in baking dish as directed; cover and refrigerate up to 4 hours. When ready to serve, uncover and bake at 375 degrees for 35 min. or until chicken is cooked through.
