What would you do with leftover Prime Rib?

I want to fix a Prime Rib Roast but there is only me and I obviously will not eat the whole thing. So do you have some ideas for leftovers?

eat it the next day

make a sandwhich or a stew, or wait, got a dog they would love it.

a hearty soup. rib sanwiches

yes,I would slice it and buy some wonderful fresh bread from paneras or fresh market and make some nice brown gravy and pour over the meat and lay on the bread i would leave it open faced and pour gravy completely over the whole thing!!
sounds YUMMY!!
Ok for a little less fattening you could also warm it up and make a nice salad by slicing it over then slicing some boiled eggs and celery and tomato throw it all together..
you kinda need crinkled up blue cheese over it for that..hubby hates blue cheese but i love it.
