In a large bowl, combine warm water, yeast, sugar, salt, and oil. Let sit to activate for about 10 minutes. Yeast should become foamy.
Add flour to activated yeast mixture. Stir together until a sticky dough forms. Cover with plastic wrap and allow to proof for about an hour (until dough has doubled in size)
Preheat oven to 425degF.
Once risen, split into two equal halves. Add one half of dough to floured surface and use a rolling pin to press out into ¼-in thick in the shape of the baking sheet. Move to parchment paper covered baking sheet. Spray with cooking oil.
