Pineapple. Deal with it.

Feta.

Oregano. For some reason, my local pizza place takes extra money for putting oregano on the pizza. No problem, I have my own supply of oregano for my pizza.

Meatballs. Have yet to see any pizzeria offer it but whenever we do a homemade pizza and there happens to be leftover meatballs, it's fantastic.

Gyro meat. It's like sausage but better. Fantastic with Canadian bacon and salami.

Also, salami.

A drizzle of honey is pretty damn good on pepperoni pizza

Butter chicken pizza! (Butter chicken sauce instead of tomato sauce)

Spinach

pickled red onions

Artichokes are so good on pizza

Wild garlic ( Bärlauch in German)

Anchovies. Salty oily goodness

Rucola, also known as arugula or rocket.

Potato.

I mean, have you ever seen potato on a pizza? I haven't.

Not a topping but mustard as a dipping sauce for my pizza crust. I’m not a crust person. But dipping dry crunchy crust into mustard almost feels like eating a pretzel.

Tastes great with pepperoni too.

Olives, Feta

Soppressata. A cured Italian meat with a tangier taste than pepperoni. It’s delicious!

Tomato.

It adds a wonderful contrast to something heavy or greasy like sausage. If I order a pizza that’s usually what I’ll get, but only at some pizza joints

Basil. Feta. Kalamata olives.

Pineapple (⁠ ͡⁠°⁠ ͜⁠ʖ⁠ ͡⁠°⁠)

I have an anti-topping suggestion: no cheese. Try it, especially if you like lots of different toppings and veg. You'll actually be able to taste them without that bitter yellow slime enveloping everything.

I'm not a vegan or anything. I just think pizza is so much better without cheese.

Shrimp.

sliced reconstituted in wine dried figs with sautéed onion.

I've been working my way through the pizzas at Pizza Artesanal.

The roasted potato and roasted pumpkin cream were two toppings that really stood out as surprisingly delicious.

Italian sausage. No, I know everyone likes it, but that's still not capturing its full glory: it is the best topping, but most people are like 'yeah it's alright but it's no pepperoni'. No, it's better than pepperoni, and therefore underrated.

green peppers.

sausage and green peppers are always in any pizza order I have to make for a party, and it's always the first to go.

Chopped hazelnuts. I add them if I ever have home cooked pizza

Peaches.

Cactus.

Egg.

Not necessarily the same pizza.

Sweet potato!

I've only seen it available at one pizza place and would get it with chicken, bacon, and a barbeque-sauce base.

Edit: The lobster pizza I had in Maine was pretty good too. They put lobster on everything up there!

Flammekueche should be more popular in my opinion
