Combine first 5 ingredients in food processor, and process until crumbs are fine; place crumbs in a shallow dish, and set aside. Combine egg whites and water in a shallow bowl; stir well, and set aside.
Place each chicken breast half between 2 sheets of heavy-duty plastic wrap, and flatten to 1/4-inch thickness using a meat mallet or rolling pin. Top each with a slice of prosciutto and a half piece of cheese. Roll up jelly-roll fashion. Tuck in sides; secure each roll with wooden picks. Dip each roll in egg white mixture; dredge in breadcrumb mixture. Place rolls, seam sides down, in a 15 x 10-inch jelly-roll pan coated with cooking spray.
Bake at 350° for 30 minutes or until done. Discard wooden picks. Cut each roll into thin slices. Garnish with basil sprigs, if desired.
Note: You can substitute 6 (3/4-ounce) slices of 97% fat-free ham, halved, for the prosciutto.
