Okay, I first saw "Pizza Americana" 2 weeks ago in Geneva. My wife says kids at the international school where she teaches also talk about it. Since then I´ve seen it on other menues. A quick google confirms it is indeed a menu fad in Europe. The article claims it started in Italy. So what is it?? Believe it or not, it is a sausage (or "hot dog") pizza smothered in French Fries! I think the following link (with photo!) says it best: "It is neither American or Pizza." But I confess --purely in the interest of cultural research-- I ordered one. It was outrageously yummy. But now I´m gonna have to eat nothing but salad for a month to get my cholesterol back down. I´m not sure if we Americans should be offended by this or gladly take the credit. :-) Happy travels!
