Leftovers Anyone?

Being that I usually am cooking for one, I have lots of leftovers. I hate wasting food, so I have been trying to come up with good ways to use the leftovers. And who wants to eat pot roast for lunch and dinner five days in a row. However, delicious it may be. So, with my pot roast leftovers i made a French dip kind of sandwich. I almost enjoyed this more than the original roast.
