Re:NJ Italian Hot Dogs via Brooklyn (along w/scrapple, goetta & pork roll)!
The Newark Italian style Hot Dog is as American as you can get. Although it's more of a sandwich than an actual hot dog, you can eat a single with one hand.
Didn't you metion that you might like the hot dog egg roll in the other thread? There's less tradition there and it certainly doesn't look like an "American" hot dog.
