Mix the breadcrumbs, parmesan, salt, and spices together in a large bowl before adding the ground chicken, egg, and sweet chili sauce (30g). Work everything together to form a large ball.
Line an air fryer basket with parchment paper before forming 12 meatballs (50 grams each) and placing in the basket.
Air fry for 8 minutes at 400ºF, flip, and air fry an additional 6-8 minutes at 400ºF until the meatballs are cooked through (165ºF internal temp).
Brush the remaining sweet chili sauce (60g) on top of the meatballs and air fry an additional 2 minutes at 400ºF.
Garnish with sesame seeds and green onion. Serve with rice and lime wedges.
