In your stand mixer or large bowl, combine water, sugar, yeast, and one cup of flour. Gently combine and let stand for 5 minutes.
Following the rest period begin to mix (use the hook attachment on your stand mixer) on low. Gently pour in remaining flour, salt, and oil. Let mix for 5 minutes on medium low speed (scraping the bowl as needed to keep the dough in the bowl). The dough will be very tacky, that's good!
Transfer dough to a large bowl (sprayed with non-stick will help) and let rise for one hour or overnight in the fridge.
As dough rises, combine tomato paste, crushed tomatoes, pinch of salt, and oregano into small saucepot. Bring to just a simmer, whisking to melt in tomato paste. Simmer covered on low for 20 minutes, then set aside for future use.
Remove dough from fridge 2 hours before cooking if applicable. Once dough is risen and warmed, preheat oven to 425 degrees. Roll out into shape of a cookie sheet (18x13), using bench flour as needed to prevent sticking. If the dough really starts to spring back and fight, go grab a glass of wine and come back in 5 minutes. Form a lip on the edges with your knuckles to make a lip. Let the dough sit in the pan to proof for 1 hour.
Once dough is proofed, gently use fingertips to work it back down (ala a focaccia bread). Top each pizza with sauce, mozzarella, pepperoni, and finish with a sprinkle of the parmesan. For a New York style Sicilian, finish the top with a line or three of sauce.
Bake pizza on the pan for 14-16 minutes or until very brown on all sides. Serve as soon as you won't burn the roof of your mouth.
