To roast the peppers on the grill, preheat the grill to 450 degrees. Wash peppers and place them directly on the grill grates. Roasting time on the grill can take 10-15 minutes until the peppers’ skin starts to brown.
Place warm and roasted chilies into a large bowl, and cover with a clean towel. Allow them to “steam” in the bowl for 30 minutes to an hour. This will help the skins come off easily.
