Not that I think is weird. I have enjoyed:
red & white sauces
various cheeses including goat cheese
garlic
tomatoes & sun-dried tomatoes
basil
various meats (chicken, pepperoni, sausage, salami, prosciutto, linguicia, Canadian bacon)
artichoke
mushrooms
black olives
spinach
arugula
red & green peppers (in moderation)
onion
pineapple
pesto
The weirdest pizza topping I’ve seen recently was French fried potatoes. That was in Venice…
