First you will need your standard cooking oil spray to spray the cooking pan with. And you will need a pizza, (any pizza will do, even one that you just made yourself.) so thats all you need to make a BBQ pizza, but you will also need your barbecue.
Step 2: Cooking your pizza
First, you put your rocks on the BBQ, (pic 1) and you put your pan on top of the rocks. (pic 2) The cooking will take around 15 - 20 minutes, just keep checking the bottom of the pizza.
Step 3: The finished product
okay, here is what your pizza should look like at the end, picture 1. And picture 2 shows the bottom of the pizza. So have fun enjoying your pizza!
