DH grills on a pizza steel at extremely high heat, no oil. We make the pizzas (sauce and top) on floured, wooden peels that DH uses to slide onto the steel. It takes less than a minute to grill them, but we like very thin crusts that brown and crisp very quickly.
My favorite toppings are mozzarella, olives, pesto, thinly sliced campari tomatoes, and fresh basil. DH likes a traditional pepperoni, mozzarella, green pepper, mushroom, and olives. No perversions, like pineapple or ham, here.
