Pull premade pizza dough from the fridge/freezer and place it on the counter for a few hours so it can come to room temperature.
Thaw mozzarella cheese, if necessary.
Place 2 pizza stones in a cold oven - one on a top rack, one on the bottom (the bottom stone will be the heating stone and the top stone will be the cooking stone).
Preheat oven to 550 degrees and let stones heat up for at least 30 minutes.
Lightly flour counter and remove dough from bag. Roll in flour.
Pull and stretch dough gently with fingers until it's slightly smaller than you want the finished pizza to be (don't overwork dough!)
Pull the top stone out of the oven onto oven-proof mitts. Carefully place stretched dough onto the stone.
Salt dough and add desired toppings.
Place stone back onto top oven rack and bake until crust is golden brown (about 7-10 minutes).
Take stone out of the oven and transfer pizza onto a cutting board.
Pull out the bottom rack stone for your next pizza. Put the first stone on the bottom rack so it becomes the heating stone.
