Pizza Shop Pizzas Recipe

In a large bowl, dissolve yeast in 2/3 cup warm water. Add 3 tablespoons oil, sugar, salt, oregano, garlic salt, remaining water and 5 cups flour. Beat until smooth. Stir in enough remaining flour to form a soft dough. Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Place in a greased bowl, turning once to grease the top. Cover and let rise in a warm place until doubled, about 1 hour. Punch dough down; divide into two portions. Roll each into a 15-in. circle. Brush two 14-in. pizza pans with remaining oil; sprinkle with cornmeal. Transfer dough to prepared pans; build up edges slightly. Bake at 425 ° for 5 minutes. In a small bowl, combine the sauce ingredients. Spread over crusts. Sprinkle with toppings. Bake for 15-20 minutes or until crusts and cheese are lightly browned.
