Ain't no such thing as a cheesesteak served on a "sub" roll. If you don't know the word, how can you know the food?!

sub roll is another term for hoagie roll

Yes, I know. But people go around calling it a "philly steak" and don't use the right word.

If you want to claim you're making a food that's a specialty of a particular city, know what it's called in that city.

Looking at recipes for cheesesteaks and chicken cheesesteaks written by people who have apparently never been to Philadelphia just makes me crazy. Even if the recipes are otherwise fairly valid.

And there's at least one that refers to it as a "Phillies sandwich." It's named after the city, not the baseball team, damnit!
