Zesty Italian Beef Sandwiches

I don't often buy roasts unless I can find one on sale for a good price. So usually, when I find one, I snatch it up and toss it into my freezer until I decide what meal I'm going to plan around it. This is one of my favorite things to do with them and to make it better, this is also one of those meals that was way better than I was expecting it to be the first time I tested it out.
