Italian Beef Sandwiches

Okay, can you stand one more? I've made this Italian Beef recipe for my family for more than 20 years. I've had friends and family request it; taken it on picnics; and fixed it for a group of hungry teenage boys more times than I can count. It's always a hit. Add a little bowl of au jus next to it for dipping; maybe some potato salad and some baked beans and you're good to go!
