Slice pork into thin slices, about 1/4-inch thick. Briefly pound pork with a pestle or meat mallet (flat side) to tenderize it. Place in a bowl.
In a small bowl, combine ginger, garlic, soy sauce, honey, rice vinegar and sesame oil. Taste and adjust to your liking. Pour 2/3 of the marinade over the pork and reserve the rest to baste the pork when cooking.
Mix the pork with the marinade and marinate at room temperature for 25-30 minutes. After that, thread onto skewers.
Preheat your air fryer at 350°F (or 180°C) as recommended in the manual. Place the skewers in the basket and then cook for 5-6 minutes. After that, open the air fryer and baste both sides of the pork skewers with reserved marinade, and then cook for another 2-3 minutes or until pork is fully cooked.
Alternatively, you can cook the skewers on the grill (or grill pan) for several minutes until fully cooked. Oil the grates well before grilling and use the reserved marinade to baste the pork while grilling.
Serve immediately with cucumber sticks (and rice, optional) on the side.
