We cooked pizza on the BBQ last week - SO impressed! Almost wood-fire pizzaish and quick and delicious...
Roll out pizza dough to dinner plate size (I like to use my breadmaker to make pizza dough - this is a great recipe too)
Oil BBQ grill and set heat to medium/high.
Place pizza dough on grill, close hood and leave for 5 minutes.
When base is browned on the bottom and puffy, remove from BBQ and add pizza toppings to grilled side of dough.
Return pizza to BBQ, this time with un-grilled side facing the BBQ grill.
Cook for another 5-7 minutes or until base is grilled and toppings are melted and hot.
If you are using toppings that need cooking time (e.g. raw chicken) it is a good idea to cook chicken before putting on the pizza. Because cooking time is fast for these BBQ pizzas, the chicken won't cook through.
