The Kentucky-based chain said the topping mosaic pizza, available only in Britain, features the image of Kate Middleton with a veil made from mushrooms and a dress comprised of cheese.
The pizza also features Prince William with a suit made from salami and peppers to commemorate the April 29 nuptials.
"Royal Wedding fever is sweeping the world so we couldn't resist having some fun and creating our very own pizza portrait of Kate and William to celebrate their forthcoming marriage," said Andrew Varga, Papa John's chief marketing officer. "Like our original crust pizza, our royal portrait is made from 100 percent fresh dough and quality ingredients, so it tastes as good as it looks."
