Unroll dough on a large baking sheet coated with cooking spray. Press dough into a 12- x 9-inch rectangle. Brush melted margarine over dough. Sprinkle with Cheddar cheese and next 3 ingredients. Cut dough crosswise into 12 (1-inch-wide) strips, using a sharp knife or a pizza cutter. Cut dough in half lengthwise, forming 24 strips. (Do not separate strips.) Bake at 425° for 8 to 10 minutes or until golden. To separate sticks, cut along perforations.
Place spaghetti sauce in a small saucepan. Cook over medium heat until thoroughly heated. Serve with pizza sticks.
