Cut bacon slices in half lengthwise. Wrap half slice of bacon diagonally around each breadstick. Combine Parmesan cheese and parsley, if desired, in shallow dish; set aside.
Place 4 breadsticks on double layer of paper towels in microwave oven. Microwave at HIGH 2 to 3 minutes or until bacon is cooked through. Immediately roll breadsticks in Parmesan mixture to coat. Repeat with remaining breadsticks.
