Poutine, Canada

On its own, the humble potato is a relatively healthy starch. But in the hands of Canadians, it becomes poutine—French fries smothered in gravy and cheddar-cheese curds. This cheesy dish is so popular that it's even sold at Burger King in Canada, where (according to the chain's nutritional information) the dish contains 740 calories and 41 grams of fat.

And that's just the traditional version. There are entire restaurants that solely serve varieties of poutine. Smoke's Poutinerie dishes up Triple Pork Poutine (with chipotle pulled pork, double-smoked bacon, and Italian sausage), Nacho Grande Poutine (with homemade chili, salsa, guacamole, sour cream, and jalapeno peppers), and Bacon Cheeseburger Poutine (with prime ground beef, double-smoked bacon, and cheese sauce).
