Ummm, ugh. This and poutine, two reasons to think that long cold winters do bad things to the human mind, not to mention palate.
Americans think cheese is a rubbery long-chain polymer which needs to be dyed orange. It's not even legally cheese, it's "cheese food" or something similar.
There's a dish in the US called Frito Pie.
Seriously, don't even talk to us about poutine -- fries, gravy, and cheese curd are at least recognizable foodstuff. Some of the shit you guys eat doesn't even meet the legal definition of food in a lot of countries.
I would just like to state for the record that, as an American, I think 'American pasteurized processed cheese food/cheese product' is an abomination, and that production of it should be stopped. I personally prefer cheddar, myself -- of varying degrees of sharpness, depending on how I'm using it -- or pepper jack cheese.
Scrapple looks kinda like charred meatloaf. I'm almost curious to try it, but I'm not sure if my stomach would enjoy the experience afterward.
Twinkies were -- ah, who am I kidding? They're pretty much the definitive junk food. (But they were better before Hostess 'came back'. Now they're smaller, rubbery, and have way less cream filling than before. It makes me sad.)
I think Frito pie is a Southern thing -- possibly just a Texan thing, since I'd never before heard about it until I saw an episode of King of the Hill wherein Hank Hill mentions 'Frito pie with Wolf-brand chilli'. I have had Wolf chilli before, though -- and, in my opinion, it's pretty terrible.
