In large bowl, mix 1 cup flour, sugar, salt, oregano and yeast. Add warm water and margarine to dry ingredients. Beat 2 minutes at medium speed of mixer. Add 3/4 cup flour. Beat at high speed 2 minutes. Stir in enough remaining flour to make stiff dough. Knead 8 to 10 minutes. Set in greased bowl, turn to grease top. Cover, let rise until doubled, about 1 hour.

Punch dough down. Divide into 8 equal pieces, shape into balls. Cover, let rest 10 minutes. Roll and stretch each ball to a 5 inch circle. Place on greased baking sheets sprinkled with cornmeal. Shape edges of each circle into a standing rim of dough. Cover, let rise until doubled, about 1 hour.

Bake at 375 F for 8 to 10 minutes. Spread each round with 2 tablespoons pizza sauce, sprinkle with cheese and your favorite topping. Bake about 10 minutes more.
