These were really great!
We added bell peppers, mushrooms, artichokes, olives and fresh basil over the basic tomato mixture and drizzled some olive oil over them before serving.
You can add a lot of different toppings as long as they are cooked ahead of time and don't need to be eaten hot.
We did have one mishap when the grill was way too hot. Those 2 pizza doughs went up in smoke in no time flat.
Cooks note: You have to find your right temperature on your grill for success with this. I strongly suggest you practice once before doing for friends or have some extra dough handy.
