Dissolve yeast in warm water in a large bowl.

Add oil, sugar, salt, and 1 1/2 cups of flour.

Beat until smooth.

Stir in remaining flour until a firm dough forms.

Turn dough onto a floured surface, cover, and let rest for 10 minutes.

Roll the dough into a 13-inch circle.

Grease a 12-inch pizza pan and sprinkle with cornmeal.

Transfer the dough to the prepared pan, building up the edges slightly.

Do not let rise.

Bake at 425°F (220°C) for 12-15 minutes, or until browned.

Add desired toppings.

Bake for an additional 10-15 minutes, or until the toppings are cooked and the crust is golden brown.
