HEAT oven to 375ºF.
SEPARATE breadsticks; cut each crosswise in half. Working with one piece at a time, stretch each to 5-inch length; tie knot at each end. Roll in cheese to evenly coat all sides.
PLACE, 2 inches apart, on baking sheet sprayed with cooking spray.
BAKE 8 to 10 min. until golden brown. Meanwhile, mix ranch dressing and hot pepper sauce.
COOL breadsticks slightly. Serve with dressing mixture.
