I've definitely witnessed Simon Uppill creating this, so it could be said to be the food of champions. He attributes this behaviour to the influence of time spent living in Falun - the Swedes will put anything on pizza, including (Swedish) meatballs.
Really?! I should be less skeptical ... No, yuck! Reminds me of a game I play with my favourite small children - we take it in turns thinking up the very worst things to have on pizza or in icecream. It starts revolting then becomes nonsensical. Great way to while away a car journey or to distract from hunger or fatigue :)
