Ingredients sprinkled among the four pizzas included Trader Joe's fresh pizza dough, pizza sauce (next time I shall endeavor to make my own), red bell pepper, yellow onion slices, live basil, pepperoni, fresh mozzarella, parmesan and romano cheeses, a small kettle grill and supremely hot coals.
It's difficult to properly cook the toppings in a lilliputian grill such as mine. (For some reason I prefer the intimacy of a tiny grill.) Given a larger unit and ample space to set coals off to the side (best for indirect cooking), thermal convection would work even better -- allowing more thorough cooking of the toppings.
Still, grilled pizza is particularly satisfying -- especially the crust char. Try it sometime. It might just blow your mind.
