If you prefer to freeze the pizzas, do not add the cheese yet. Bake the cheese-less pizza for 10 minutes. Remove from oven and let cool. Sprinkle with cheese. Cover with plastic or foil to protect from freezer burn and freeze in a plastic container or box. When ready to serve, remove from freezer. Place on a pizza stone or on the oven rack and bake at 375°F for 20- 25 minutes.
