Set the oven rack to the lower position. Preheat to 500ºF (260ºC). Lightly brush a large baking sheet with olive oil. Evenly sprinkle cornmeal on the pan if desired.
On a lightly floured surface, stretch and shape the dough into a 10-inch circle.
Transfer dough to the baking sheet. Use fingers to press into a 12-inch circle. Leave the edges slightly thicker, about ½-inch tall and wide.
Brush some olive oil on the edges of the dough to make the crust crispier when baked.
Spread the sauce on top, followed by the cheese, and zucchini. Sprinkle the Italian seasonings on top, and some salt and pepper.
Bake the pizza on the lowest oven rack until the crust is golden brown, and the cheese is melted and bubbly, about 10 to 12 minutes.
Sprinkle some red pepper flakes (if using) and parmesan cheese on top.
