Make sure to season your skillets before hand.
Put yeast, sugar, salt, and dry milk in a large (2 qt.) bowl. Add water and stir to mix well. Allow to sit for two minutes. Add 2 tablespoons oil and stir again. Add flour and stir until dough forms and flour is absorbed. Turn out on to a flat surface and knead for about 10 minutes. Divide dough into two balls. In the two 12 inch skillets, put 4.5 Oz. (1/4 cup and 1 tablespoon) of oil in each making sure it is spread evenly. Using a rolling pin, roll out both balls to about a 13" circle. Place in skillets, pushing excess up the sides of the skillets. Spray the outer edge of dough with Pam. Cover. Place in warm area and allow to rise for 1 to 1 1/2 hours.
For Each Twelve Inch Pizza: Preheat oven to 475ºF. Spoon 1/2 cup sauce on dough and spread to about where the dough turns up the side of the skillet. Distribute 2 1/4 Oz. shredded mozzarella cheese on sauce. Place toppings of your choice in this order: Pepperoni or Ham Vegetables, Meats (cooked ground sausage or beef). Top with 4.5 Oz. mozzarella cheese. Cook until cheese is bubbling and outer crust is brown.
