In a small bowl, combine the Parmesan cheese, Italian seasoning, garlic powder and rosemary; set aside. Cut pita breads into 1-in. strips; split in half. Spritz crust side with butter-flavored cooking spray; place crust side up on a broiler pan coated with cooking spray.
Broil 3-4 in. from the heat for 1 minute. Turn; brush with butter and sprinkle with Parmesan mixture. Broil 1-2 minutes longer or until golden brown and crisp.
