In a large bowl, combine ground pork, ground beef, panko, egg, garlic, ginger, and salt. Mix until just combined and form into 20-24 meatballs.
Arrange meatballs in air fryer basket in a single layer (work in batches if needed). Air fry at 380°F for 10-12 minutes, shaking basket halfway through.
While meatballs cook, whisk together sweet chili sauce, soy sauce, and rice vinegar in a large bowl.
Transfer cooked meatballs to the bowl with sauce and toss gently to coat evenly.
Return glazed meatballs to air fryer for 2 minutes at 400°F to caramelize the glaze. Garnish with sesame seeds and green onions.
