Add yeast, sugar and warm water to the bowl of stand mixer. Give it a quick stir and let sit until yeast gets foamy.
Add salt, oil and about 2 cups of flour. Mix on low, adding the remaining flour slowly until it is all Incorporated. The dough will look a little shaggy. Shut off the mixer, and knead it by hand to mix in any dry bits from the bottom of the mixer. If the dough is still too dry, knead by hand a few times with wet hands.
Allow the mixer to knead the dough for about 5 minutes. I stop the mixer periodically and flip the dough around so it kneads it evenly.
Place dough in an oiled bowl and cover with plastic wrap. Allow to rise for 30 minutes.
Separate dough into 3 equal parts, and roll each out to about a 12 inch circle.
Place on hot pizza stone, add ⅓-½ cup of sauce, 1 cup of cheese and whatever toppings you like. Return stone to oven and bake for 10-12 minutes.
