Today has been sort of an unofficial pepperoni day here on Slice, and, with the Super Bowl coming up on Sunday (the biggest pizza-delivery day of the year), I thought I'd draw your attention to a Slice classic that might help you narrow down your ordering options come game day. Our Delivery Pepperoni Pizza Showdown ranks four of the biggest chain pizzas on crust, flavor, and pepperoni distribution. Give it a look-see before you pick up the phone.
