Last May, there was a special "Sandwich Day" episode on 30 Rock. In a climactic scene, Liz Lemon, Tina Fey's character, rushes to the airport to catch her then-crush Floyd, but gets stalled at the security gate—her sandwich's dipping sauce exceeded the three ounce limit. "I can have it all," she says, choking it down before racing after Floyd. Almost a year later, and Caroline of Devil and Egg still wants to know the juicy sandwich's origins.

If you troll around the interweb, you'll read a lot of people theorizing that it's Defonte's in Red Hook, Brooklyn, which now has a location on Third Avenue in Manhattan. But in a happy and one might say, karmic, coincidence, I happen to have a very good friend who's husband works on the set of 30 Rock.

That friend's husband's arms were twisted, and Eureka! Turns out it's from Fiore's Deli in Hoboken, New Jersey. A close-up of the sandwich, after the jump.

Robyn remembered that we had tried the sandwich last summer, and found this glossy shot of hers.

The sandwich anatomy: a long Italian loaf, roast beef made in-house at Fiore's, fresh mozzarella also made in-house, roasted red peppers, and a side of gravy made from the roast beef's drippings ("so good you could drink it").
