If using bamboo skewers, soak them in water for about 15 minutes to prevent burning on the grill.
Cut the chicken breasts into bite-sized pieces and place them in a mixing bowl.
In the bowl, add the vegetable oil, salt, black pepper, garlic powder, and paprika. Toss well to coat the chicken evenly.
Thread the chicken pieces onto the skewers, leaving a little space between each piece for even cooking.
Preheat your grill or grill pan over medium-high heat. Grease lightly if necessary.
Grill the skewers for about 10-15 minutes, turning occasionally, until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
While the chicken cooks, prepare the Bang Bang sauce by whisking together the mayonnaise, sweet chili sauce, sriracha, and lime juice in a separate bowl.
Once the chicken skewers are cooked, remove them from the grill and drizzle or dip them in the Bang Bang sauce.
Garnish with sliced green onions and fresh cilantro before serving.
