i've done grilled pizza a few times with fresh dough. very tricky as you need the grill to be screaming hot. it can be done on gas but nothing competes with the taste of charcoal imo, that smokey flavor is great! for this method of prep the dough has to be worked extremely thin, and brushed with oil. now it's kinda similar to grilling delicate fish in that once you throw it on the grill you have to let it do its thing, because if you start messing with it too soon its all over, the dough wil let you know when its ready to be flipped as it should pull away cleanly. add whatever topping you like and heat them through and time to eat!
