Chopped Steak Grilled Cheese

There is nothing particularly fancy about this dish, but it’s a perfect use for leftover flank steak. The key is to make sure you use sturdy bread and also chop up the steak into bite-size pieces. Dicing the steak makes it easy to take a bite of the sandwich without pulling out a huge strip of steak. For 15 minutes of work, I’m not sure if it gets any better than this.
