To start making the dough, mix the yeast, sugar, and water in a bowl. Let it sit for five minutes, then add your flour and salt. Now it’s time to knead.
Using a standing mixer (or your hands), knead the dough until thoroughly combined, then cover with wet towel or plastic wrap and let sit at room temperature until it's doubled in size (approx 1-2 hours).
Season your skillet with olive oil, cornmeal, oregano, salt and pepper. Mix this thoroughly and from edge to edge of the pan. Spread the dough across the pan and let it sit in the pan until puffy (about 30 mins).
In the meantime, make the sauce by mixing the tomatoes, olive oil, sugar, and optional basil. While it might feel un-natural, spoon the sauce across the dough from edge to edge, without a bare rim.
Turn on your stove's largest burner to medium-high heat and cook the pizza for about 5 mins.
While you wait for the pizza to cook, this is also a good time to pre-heat your broiler to high.
Once you start to smell the dough getting crispy, add cheese and toppings, and cook until the bottom gets golden (can lift and check the bottom with a spatula - approx another 2-3 mins)
Transfer the pan to the highest rack in the pre-heated broiler and cook until the cheese is browned but not burned (approx 4-5 mins).
Take out your pizza, let it cool in the pan until firm. Then remove it with tongs, and enjoy!
