Just take your basic pizza dough recipe and instead of the oven, do it on the BBQ!
Simply get the bbq very hot, then turn one side to very low, leaving the other side on full. Place the dough directly on the grill on the low side for about two minutes. Remove from the bbq, flip dough over, add
the toppings of your choice, and put back on the grill for about five to eight minutes.
The first step of the two minute cook on the one side can be done a couple of hours ahead so that if you are doing these for a group, you don't have too long to wait.
To make Focaccia bread, shape the dough into foil pie plates. After they have risen the required amount of time, they can be cooked on the bbq the same as in an oven, assuming that your bbq has reasonable
temperature control. Place the foil pan on what is usually used as the bun warming rack, or as with the pizza, turn one side low and leave the other sufficiently high to give a temp of around 375 - 400. The Focaccia in the foil pans also freeze very well. Simply shape the dough and put into the oiled pan, then place it in a well oiled zip lock bag and freeze. When you are ready to use, remove from the freezer and bag, cover and let it thaw out -- takes several hours -- dimple it, spread olive oil on it, sprinkle with salt, pepper, herbs, olives or whatever you use, and bake it when it has risen enough.
