Anything you like, but to stay classic, follow the traditional approach of simple Pizza Sauce, fresh mozzarella and fresh basil. You can add the basil when it comes out of the oven, but in Italy it is most often added before.   The amounts of sauce and cheese given below is generous for your 4 pizzas. In fact, you might not use the entire amounts. Use our images to help you assess. In general, a Neapolitan-style pizza is very lightly topped. If you want a toppings-heavy pizza, try our Deep-Dish Pizza!
