It CAN be laid directly on the grate, but mine is never clean enough in my opinion for that. I have a 9 x 13 rack that goes in a lasagna pan for broiling (which i never do... but I digress...) I lightly oil the rack, and put the dough on the rack, then place it on the grill. You have to watch it carefully b/c it cooks so fast. Flip the dough, so the uncooked side is face down, and add your sauce, cheese, and COOKED toppings. Let it cook until the dough is cooked and the cheese is melted. Since learning to cook pizza this way, I've found aluminum sheets that are full of 1/4" holes. They're about 10 x 15, perfect size to go on the grill. They can be found in the grilling section at Walmart. It's much easier to use these, lightly oiled, and I can rotate them to get 2 pizzas done in record time. It's important to have the sauce, cheese and cooked toppings ready to go b/c it cooks so fast. The crust is so tasty when cooked this way, and has a fantastic texture.
