I worked at quite a few pizza places back in the day ....and I had this combo of toppings that I loved and called it the 'Backhand, forehand, top shelf' after the first goal Gretzky scored as a Blue's player. Anyway...the ingredients are:
On Thin "St. Louis Stlye" Crust
Sausage, Pepperoni, Ham, Bacon, Pepperoncini's, Jalapeno's....then a layer of granulated garlic, crushed red peppers and pepper sprinkled on it prior to going into the oven. Mix of Mozzarella and provolone cheese. Sucker was nice and spicy.
I agree with EB that single topping pizzas are boring and a waste but in a setting where you're feeding dozens of people it's the safest way to go.
