Preheat oven to 350°.
Heat oil in a small skillet over medium heat. Add garlic, and cook, stirring often, 1 to 2 minutes. Remove from heat, and stir in rosemary and salt.
Unroll dough, but do not separate into strips. Use a pastry brush to spread garlic mixture evenly across surface of dough. Working with each one at a time, tear breadsticks along the perforations, and twist each strip. Stretch slightly, and place on a baking sheet. Bake at 350° for 13 to 15 minutes or until golden.
