So, why is it that (some) people insist on putting more carbs as the topping for pizza? Fundamentally, that's when you get bad (aka, "New Zealand-style") pizza.
Pizza already has ... um ... you know, bread? So the idea of adding pasta, or French fries, or doughnuts, as a topping to pizza goes against the very premise of pizza. It's nonsensical, like, "Good bard," or "Evocative and literary Dragonlance book."
This is why you will see toppings for pizzas usually divided into two types-
1. Meats.
2. Veggies.
Sometimes, you get more cheese, or different kinds of cheese, or Greece's sole contribution to Western civilization, Feta cheese ... but do you know what you never see?
3. Moar Karbs!!!!!!
