1 package active dry yeast
1 teaspoon sugar
1 cup warm water (105 to 115 degrees)
2 Tablespoons vegetable oil
1 teaspoon salt
2-1/2 to 3-1/2 cups flour (may be made with 1/2 wheat flour)
olive oil
cornmeal

In a large glass bowl, sprinkle yeast and sugar over warm water. Stir until dissolved. Stir in oil and salt. Add enough flour to make a soft, but not sticky dough. Turn out onto a well floured surface. Knead until smooth and elastic, adding a dusting of flour as necessary to prevent stickiness. 

Spray a second glass bowl with cooking spray. Place dough in the bowl, then turn the dough over, so that the top of the dough is lightly coated with cooking spray. Cover with plastic wrap and place in a warm place to eise until almost doubled, about 45 minutes.

Punch down dough, knead on a floured surface for about a minute until no longer sticky.

Stretch or roll into pizza pans that have been sprayed with cooking spray and dusted with cornmeal.

Pierce dough with a fork several times, brush with olive oil and partially pre-bake crust for about 6 minutes at 400 degrees before adding toppings.

Remove from oven, add sauce and toppings. Return to oven and bake an additional 10 minutes or so until the crust is lightly browned and the cheese is melted and bubbly.
