Here in the U.S. yogurt refers to a specific type of dairy product.
Fish and chips were mentioned; what you call "chips" in that dish, we would call "French fries", and what we call "chips" are "crisps" in England. Of course, they do share a common ancestry; crisps were invented by a cook deliberately slicing his fries too thinly to get back at a customer who kept complaining about sogginess.
As mentioned before, here in the southern U.S., "Yankee" refers to someone from up north, and "Coke" can refer to carbonated beverages in general (though in careful writing, "soft drinks" would be used).
As for pies, most of the pies we eat are dessert pies (apple pie, pecan pie, pumpkin pie, etc.). The only exception I can think of is the chicken pot pie (no, not that kind of pot).
