Preheat air fryer to 375F / 190C.
In a large bowl, combine cream cheese, mozzarella, chopped bacon, garlic, and green onions.
In a small bowl, combine salt, pepper, and Italian herbs. Set aside.
Using a sharp knife, cut slits into each chicken breast to create a pocket. Be careful not to cut all the way through.
Season the inside and outside of each chicken breast with the dry seasoning mixture.
Scoop a quarter of the cream cheese mixture and "stuff" into the pocket of each chicken breast. Use toothpicks to keep them closed.
Wrap each chicken breast with 1 ½ strips of bacon. Secure the bacon with a toothpick.
Lightly spray the air fryer basket with oil, then place the wrapped chicken into the basket. Make sure there is space between them (you may need to cook in batches).
Cook for 15-20 minutes, or until the internal temperature of the chicken reaches 165F / 94C.
Remove from air fryer and allow the chicken to rest for 5 minutes before serving.
