I'm Sad I Never Got to Try Japan's 646-Calorie-Per-Slice Pizza Hut Double Roll

Remember this disgusting specimen? It was Pizza Hut Japan's Double Roll Pizza, and it packed a whopping 646 calories… per slice. Good lord. Wait 'til you see the list of toppings.

What contributed to such a high calorie count? Try little bacon wrapped sausages that acted as the crust, and mini hamburger patties on top of the mushrooms, soy beans, corn, paprika, garlic chips, green peppers, and pepperoni. Oh, and cheese? Yeah, it has cheese. Mozzarella, cheddar and parmesan. Oh, and it comes with ketchup and maple syrup for extra flavor. I wonder why it's not around anymore?
