Step 1: In a medium bowl, whisk together the mayonnaise, sweet chili sauce, Sriracha, honey, lime juice, minced garlic, and grated ginger until smooth.
Step 2: Place the cubed chicken in a large bowl and season lightly with salt and pepper. Add about 1/3 of the bang bang sauce and toss to coat thoroughly. Let marinate for at least 15 minutes.
Step 3: If using wooden skewers, ensure they have been soaked in water. Thread the marinated chicken pieces onto the skewers, leaving a small space between each piece.
Step 4: Preheat your grill or grill pan to medium-high heat. Lightly oil the grates to prevent sticking.
Step 5: Place the skewers on the grill and cook for 5-6 minutes per side, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
Step 6: During the final 2 minutes of cooking, brush the remaining sauce generously over all sides of the skewers until they are glazed and slightly charred.
Step 7: Remove from the heat, garnish with fresh cilantro and sesame seeds, and serve immediately.
