Place a large baking sheet or pizza stone on the top rack of your oven and preheat to 450° convection bake.
On a cutting board, prepare and slice all toppings, including veggies, cheese and pepperoni.
Prepare a pizza peel or another cutting board with a generous sprinkling of cornmeal.
On another floured cutting board, roll out the first ball of dough with a rolling pin (don't worry that they have expanded and grown together, just pull or cut back apart). Add flour as needed. Get it as thin as you can, about the size of the pizza peel.
Transfer dough to the cornmeal covered peel. Top with sauce, cheese and toppings.
Making sure the pizza slides around on the cornmeal, transfer the pizza to the hot pan in the oven. You can take the pan out and set it on the stovetop if that is easier. If any part sticks, carefully release it with a spatuala.
When pizza #1 is in the oven, make pizza #2. When pizza #2 is ready to go into the oven, pizza #1 probably won't be quite done, but the crust will be firm enough to transfer to the oven rack. With two spatulas, carefully pick the whole pizza up and put it directly on the oven rack below. This will finish cooking, giving you a nice crispy crust. Now your pan is free to slide in pizza #2.
While those two are cooking, make pizza #3. By the time you are ready to add #3, pizza #1 is probably done. Remember your oven is really hot, so check on it and don't let it burn. Take it out, slice and serve on a cutting board. Now transfer pizza #2 to the bottom oven rack and pizza #3 to the sheet pan. Make pizza #4 and transfer them all through the oven using this same method.
You did it! And it all gets easier with practice! Enjoy!
