In a stand mixer, combine warm water, yeast and sugar in a bowl and allow to sit and proof for about 10 minutes. It should expand and develop a frothy bubbled top.
Carefully add flour, salt, seasonings and oil to the bowl and use a dough hook to knead the dough for about 3 minutes until the dough forms a nice ball and has cleaned the sides and bottom of the bowl.
Divide the dough into 4 equal balls. Place into a dish that has been sprayed with nonstick cooking spray and cover with plastic wrap. Set aside for 2 hours to rise.
Heat your grill up nice and hot between 450-500 degrees preferably.
On a lightly floured surface, roll each of your dough balls out using a rolling pin or just your hands.
Once the grill is hot, carefully lay the rolled dough on the grill grate and close the lid for about 2 minutes.
Use a large spatula or pizza paddle to flip the pizza crust grilled side UP on a plate and return inside to add your desired toppings. Turn the grill temperature down to a medium low now and carefully transfer the pizza back to the grill. Close the lid and let it cook for another 5-10 minutes depending on the thickness of the toppings.
