Unroll breadsticks. Cut each breadstick in half crosswise, forming 3 1/2-inch pieces; cut each portion in half lengthwise, forming 1/2-inch strips. Place on lightly greased baking sheets. Coat with cooking spray, and sprinkle with dressing mix.
Bake at 375° for 10 to 12 minutes or until lightly browned. Serve with spaghetti sauce.
