Society has collectively decided that pepperoni is the default pizza topping. Nearly every advertisement for a pizza chain will display pepperoni pizza in lieu of any other toppings.
Pepperoni doesn’t deserve this reputation. It adds nothing to a pizza besides what can only be described as a mildly spicier, yet inferior, version of salami. If you want dried meat on your pizza pie, just slice up a roll of salami and throw it on top of your cheese.
There’s also the matter of grease. There is no need to add to the risk of health complications by throwing pepperoni onto your pizza, especially since these highly-concentrated volumes of fat that pool into the pepperoni are consumed with every bite.
