I know traditionally Hoagie is simply the Philly name for a sandwich (basically an Italian hero). I know it's a regional name, but as a NYer who has had Italian combo sandwiches in a few states and areas, there is something taste specific to a hoagie. I have family from Philly and we recently got a hoagie (it was called this on the wrapping) at Wegman's in Ithaca, NY. Tasted just like a true Philly hoagie.
Any ideas what gives it the distinct taste?
