1Slice your green onions into very thin long strips, and chop your chicken into 2-inch cubes.
2In a bowl, add your chicken, white pepper, minced garlic, minced ginger, Shaoxing wine, only the whites of an egg (no yolk), and soy sauce and mix well and set aside.
3On a plate, pour your coarse potato starch. Dip your marinated chicken nuggets until it is fully coated with potato starch.
4Spray your air fryer with cooking oil, place your chicken coated with potato starch inside the air fryer, and spray it with a quick light coat of spray oil.
5Cook in your air fryer at 390°F, flipping halfway through or until crispy and golden brown.
6In a small bowl, mix together wasabi, brown sugar, soy sauce, rice vinegar, water, and lemon juice to make your sauce.
7Once cooked and crispy, plate half your chicken nuggets, top off with half your thin sliced green onions, and pour half your sauce on top and enjoy.
