My son worked at a Chicago hot dog and Italian beef sandwich stand in the old neighborhood. When we were moving away his boss, Sid the Stand Man, told him what to do to get Italian beef sandwiches made at home as close as possible to his stand's taste. Since it's not really a "recipe" as such, please excuse the way I'm explaining how to make these "blast from the past" sandwiches that I've been making for 20+ years now! This recipe is for a crowd, but I have made them using a smaller inside round roast allowing for 3 or 4 sandwiches per lb. of roast.
