Preheat oven to 400ºF (200ºC). Sprinkle flat Rectangle Pizza Stone with cornmeal; set aside. Combine flour, yeast, sugar and salt in medium mixing bowl. Add water and oil; stir until mixture forms a ball.
Place dough on lightly floured surface; knead until smooth and elastic, 3‑4 minutes. Cover; let rest 10 minutes.
Place dough in center of prepared baking stone; roll within 1 in. (2.5 cm) of edge. Spread pizza sauce onto crust to within 1/4 in. (6 mm) of edge. Top with assorted toppings, if desired; sprinkle with cheeses. Bake 16-18 minutes or until crust is golden brown.
