Whisk mayonnaise, Thai sweet chili sauce, Sriracha, and honey in a bowl. Reserve half the sauce for later.
Place skewers in pressure cooker basket/trivet with water underneath. Cook on high pressure for 6 minutes.
Let pressure natural release for 5 minutes followed by quick release.
Optional: Grill or pan sear skewers for 1-2 minutes to caramelize and brush with reserved sauce before serving.
Notes
Store leftover skewers in an airtight container for up to 3 days. Freeze cooked chicken (off skewers) up to 2 months. Reheat gently. Keep sauce separately in a sealed jar.
