Preheat the oven to 350°F and spray an 8x8 pan with nonstick spray.
In a large bowl, combine ground chicken, green onions, egg, lime zest, panko breadcrumbs, cilantro, ginger, lemongrass, garlic, and salt. Mix together until well combined.
Shape the mixture into 2 tablespoon-sized balls and place them in the prepared dish.
Bake for 10 minutes. Then remove from the oven and baste the top of the meatballs with sweet chili sauce.
Return to the oven and continue to cook for another 5-10 minutes or until the meatballs are fully cooked through and the sweet chili sauce becomes sticky.
Serve hot with additional sweet chili sauce for dipping.
