Punch the dough down again and roll into a ball, then let rest for 30 to 60 minutes.
Heat grill to medium.
Roll the dough into desired shape, approximately 1/2-inch thick and coat it with olive oil before putting on the grill over indirect heat. Grill to desired level of color, approximately 10 to 12 minutes.
