In the bowl of a stand mixer add the warm water and sugar, then sprinkle the yeast over the top. Allow to rest about 5-10 minutes as yeast proofs.
Add the flour, oil, and salt to theyeast mixture stirring until just combined. Then use the dough hook, or your hands, and knead the dough for about 5 minutes. It should be smooth and elastic, with a little tackiness to the dough.
Place the prepared dough into a large metal bowl, that has been greased with butter, then cover the top with plastic wrap. Allow the dough to rest in a warm place until it has doubled in size.
Prepare to baking sheets by lining them with parchemnt paper.
Once dough is doubled turn it out onto a lightly floured surface. Use your hands to pat the dough into a large circle. Cut the circle of dough in half, then cut those two pieces in half again. You should have four pieces of dough, cut those four pieces of dough in half again. Now you should have 8 pieces (if you want large buns stop here) finally cut those pieces in half so you have a total of 16 dough pieces.
Working one piece at a time, roll the dough into a rough ball then stretch into a circle. Repeat this process with all the remianing dough. Once that is finished start back at the first circle and gently stretch the dough so you have a final circle that is about 4-5" in diameter, repeat this with all the dough circles.
Now top each bun with about 1 tablespoon of pizza sauce and spread it into an even layer using the back of the spoon. Repeat this process with all 16 buns. Finally top each bun with a generous amount of shredded cheese.
Allow the prepared pizza buns to rest about 20-30 minutes,until the edges are just starting to look puffy. During this time preheat your oven to 375 and make sure your oven racks are in the upper and lower third of your oven.
Once the buns are ready place one tray up, and one tray on the lower rack of your oven and bake for 10 minutes. Switch the up and lower tray positions and allow to bake another 10-15 minutes.
Remove the buns from the oven and allow to cool for a few minutes before removing from tray to serve.
