When I first heard of it, I thought they were talking about pizza with a side of fries. Which would be bad enough. But noooooooo. The French fries are on top. Even worse, there is a variant (or let's call it a mutation) with fries and hot dogs (as seen in the alarming photo).
It shouldn't come as a surprise that this is well-beloved of teenagers. But it certainly doesn't bode well for the future of Italian cuisine, if this is what the young people like.
It may seem counterintuitive, but potatoes are not bad at all on pizza as a topping. But I like them thinly sliced and roasted, with other veggies and olive oil.
