Tough question. Since I do not consider the crap Pizza Hut sells to be Italian food, let alone Pizza, I suppose you could be a real Italian and order it, although I have no clue why anyone would want that crap.
On the other hand if you ordered and ate it, and claim it is Pizza, then you cannot be Italian!
Like a dellocroce said it cannot change my ethnicity so I'm still Italian but maybe not a super italian. I also confirmed this with the Sons Of Italy.
