Make the dough: Combine yeast, water and sugar in a large mixing bowl. Allow yeast to proof for five minutes.
Add 1 cup flour. Mix with wooden spoon or dough whisk.
Add olive oil, salt and remaining flour. Mix until dough comes together and pulls from the sides of the bowl.
Dust hands with flour and knead dough in bowl (or on lightly floured counter top) until smooth and elastic, about 2-4 minutes.
Cover bowl with plastic wrap and allow dough to sit in warm spot until doubled in size, about an hour.
Preheat oven to 425°F.
Lightly flour a sheet pan (10x14-inch) and your hands. Punch down dough and place on prepared sheet pan. Stretch out dough until it completely covers pan, leaving a bit of a crust around the edges.
Ladle sauce on dough, spreading evenly over top of dough. Sprinkle with shredded cheese and toppings of choice.
Bake for twenty minutes until crust and cheese are golden brown.
