Last night we made 4 great pizzas on the grill with the help of a pizza stone and this other flat metal pizza grill pan with holes in it.
We built our pizzas on a peel..
Started them on the metal grill pan
Then transferred to the pizza stone. Keep the grill at approximately 450 or so. You will need to know your grill and turn the pizza if the back is hotter than the front. This will cook all your meats, onions, etc as if it were in a regular oven.
The result was amazing and this time we took a shortcut and used pre-made dough from Fresh and Easy. They were fantastic. My friend Campbell here is getting really good at this.
