Not knowing much about something I have very strong opinions on….
Remember that with authentic Italian pizzas, less is more in terms of the toppings. This is true of most Italian cuisine. The ingredients are carefully chosen to compliment each other as well as possible.
Many pizzerias in Naples only serve a couple of different pizzas. Whilst I think that there are other great combinations, I do think it’s a great starting point to take a look at the traditional Italian pizzas and their toppings.
