Fine, but what if you don't live within 2000 miles of the sandwich?
My wife used to get these when she was at Ft. Dix NJ and out of the blue she brought home a frozen version. It's made by Fast Fixin and is called Philly Beef Steak. Cooks up fast.
I'm not going to say it's as good as the real thing but it's not bad.
So maybe if you find yourself way far away from one this might get you through the withdrawals.
