Preheat the oven to 200 degrees C (390 degrees F) and lightly grease a roasting tin with oil or cooking spray.
In a large bowl, mix together the barbecue sauce, chili sauce, soy sauce and black pepper. Add the chicken and mix until fully coated.
Transfer the mixture to the prepared roasting tin and spread into 1 even layer. Bake until the winglets are cooked through and golden, 15 to 20 minutes. Transfer to a large serving platter and garnish with the spring onions, cilantro and lime wedges.
