This recipe was given to me 35 years ago as a beef romanoff dish. The dish required sour cream and cooked noodles added to the gravy. It was delicious but not my family's favorite dish. I adjusted the recipe to suit my family's taste by eliminating the sour cream and noodles and by slicing the roast very thin, placing the meat inside a hot yeast roll, serving with a small dish of gravy for dipping. After serving this to my son-in-law 16 years ago, this dish has become one of his favorite request when he visits. This meal is sliced roast beef in a large hot yeast roll served with the gravy for dipping. The gravy will not be thick.
