You are ground beef. Very meaty and filling, it is enjoyable to see you on the pizza... But as I eat a pizza with ground beef on it, I begin to realize how disgusting this discount cheese steak is and don't eat anything for the rest of the night.
You are pineapple. Your sweet, tangy flavor is undermined by many when you're on a pizza, leading to a polarizing view of you despite your health benefits. Also, medicine men use you to induce labor.
You are shrimp. You don't belong on pizza but an alarming amount of people will put you on it anyways instead of putting you to good use with a good coconut coating and a fryer full of peanut oil.
You are both kinds of olives! The best of both bitter worlds rolled into a single pickling jar best served with savory cheese and cured sausage, but for some reason people still put it on pizza.
You are pepperoni. One of the best toppings out there, it has a strange tangy--HEY WAIT A SECOND! This isn't real pepperoni! This is vegan pepperoni! It's fake pepperoni! You're fake!
You are garlic. The best ingredient for the pizza, you are cool, savory and have a punch not unlike your onion cousin who usually takes the limelight. Without you, Italian culinary arts would be dead and gone.
