My Prime Rib Disaster Story
Now apparently the trick to having enough of your leftover prime rib roast is to NOT leave the cut prime rib out on the counter with a still-in-training puppy around.
Our 4-pound portion got cut down to about a pound and a half in the blink of an eye. I'm telling you, I had barely walked into the kitchen adjacent office. My golden retriever Thor must have used his ninja dog skills. Meanwhile, the older black lab was laying where I had left her...but looking like she knew the storm was coming!
My best-cut slices were gone, but the smaller pieces and ends are still wonderful. We embraced the mishap and watched the movie A Christmas Story so we could giggle when the Bumpus dogs steal the Christmas turkey.

Since your prime rib roast has already been cooked, this recipe is as easy as it gets! You'll need a saucepan, skillet, and a ladle to get started!
With 1½ pounds of leftover prime rib, you can prepare about 4 sandwiches. Of course, this amount will vary based on how much meat you have!
