When the oven is ready, dust a pizza peel with cornmeal or semolina flour. (If you don’t have a pizza peel, you can use a rimless baking sheet or the back of a rimmed baking sheet. But a pizza peel is well worth the investment!) Stretch the dough into a circle; see How to Stretch Pizza Dough for instructions. Then gently place the dough onto the pizza peel.
Quickly assemble the pizza. Spread the pesto over the dough, sprinkle on as much cheese as you like, add the tomato slices, and top with some fresh grated Parmesan and a pinch of salt.
Use the pizza peel to carefully transfer the pizza onto the preheated pizza stone.
Bake the pizza until the cheese and crust are nicely browned, about 5 to 7 minutes in the oven (or 1 minute in a pizza oven). Try to let the pizza cool before you eat it, so you don’t burn off all your taste buds – this is always the hardest part!
