Dissolve yeast in warm water and let proof for about 5 minutes.
Add oil and dry ingredients to yeast mixture. Mix and form dough into a ball. Let rest for 5 minutes.
Transfer dough to a well floured board and knead for about 10 minutes.
Place dough in a lightly greased bowl, turn once to coat both sides and cover with plastic or a kitchen towel. Let rise in a warm place until doubled, 1 to 2 hours.
When ready to make crusts, preheat oven to 450°F. Punch down dough and divide into portions for each crust.
Roll to desired size on a floured board and then transfer to prepared pizza pan.
Bake at 450°F for 10 minutes. Remove from oven.
Put sauce and toppings on pizza crust; cover with cheese (if desired) and bake an additional 20 minutes, until pizza is done.
