Unroll the pizza dough and use a pizza cutter to cut the dough into six strips.
Place one pieces of string cheese on the bottom of each dough strip.
Top the cheese with four slices of pepperoni.
Fold the other end of the dough strip over the top of the pepperoni and cheese. Stretch the dough slightly to cover the pepperoni, then press the sides together to seal as best you can.
Place the stuffed breadsticks in the air fryer.
Brush each breadstick with butter and top with parmesan cheese, garlic powder, and Italian seasoning.
Cook the breadsticks on 350° for 6 minutes and check for doneness. Cook for longer if not done and check every 1-2 minutes.
Serve immediately with marinara and enjoy!
