Hmmmm......I would roast it for a long time at a low temperature. Salt and pepper for sure.
Then I would grind it all up with some mayo, more salt and pepper, dill pickle relish, a bit of sugar, and some grated carrot.
Make it all into lunch meat, make lots of sandwiches. Take those sandwiches with you as you go out and pick up cans and bottles.
Soon enough you will have plenty of money to buy a proper Prime Rib Roast.
