Pepperoni and pizza, a deliciously mouth-watering, gooey combo right out of pizza heaven! It’s something to consider on National Pepperoni Pizza Day, which is tossed up every September 20. Pizza might be most heavily associated with Italy, but the pepperoni pizza is purely American. Served on more than a third of American pizza orders, it’s safe to say that pepperoni is the U.S.’s favorite topping, and that’s a reason to celebrate. So, today, get up to your local slice shop and get down with National Pepperoni Pizza Day!
