Leftover beef, any suggestions?

[Caslon]

If you have a meat slicer, you can slice it up super thin for Au Jus sandwiches.

I buy some powdered Au Jus mix, some already made dinner rolls, coleslaw kit (includes the dressing) and some frozen french fries. I mix up the coleslaw, make my Au Jus mix, bake the french fries. I pile the thinly sliced roast beef onto heated dinner rolls and then slice them diagonally for ease of dipping. I put the Au Jus gravy in a small 300ml glass bowl for dipping into. It's makes a great Saturday nite dinner for me.
