01 - In a bowl, toss chicken cubes with vegetable oil, garlic powder, soy sauce, black pepper, and salt. Marinate for at least 10 minutes, or up to 2 hours refrigerated for deeper flavor.
02 - Thread marinated chicken pieces onto skewers. If using wooden skewers, soak them in water for 20 minutes prior to prevent burning during grilling.
03 - Preheat a grill or grill pan to medium-high heat, approximately 375-400°F.
04 - Grill chicken skewers for 10-15 minutes, turning occasionally, until the chicken is cooked through with an internal temperature of 165°F and slightly charred edges.
05 - While the chicken cooks, whisk together mayonnaise, sweet chili sauce, sriracha, honey, and rice vinegar in a bowl until smooth and fully combined.
06 - Transfer cooked skewers to a serving plate. Brush liberally with Bang Bang sauce or drizzle over the top. Sprinkle with sesame seeds, scallions, and cilantro. Serve immediately.
