Preheat grill with burners on high and pizza stone inside. Ideal is 500-600 degrees.
Cover board with 75% all purpose flour and 25% cornmeal and push and stretch crust out into a big circle, incorporating some of the flour on the board into the dough which will help keep it from sticking to your hands.
Add sauce, toppings, and cheese. Make sure pizza can slide back and forth on board. If it can't, add more cornmeal.
Slide pizza onto pizza stone and close lid.
Cook for ~12 minutes, until crust is crispy and toppings are bubbly.
Slide pizza off using a large spatula or pizza lifter.
Allow to cool slightly and slice!
