Very thinly sliced top round, which happened to be 'reduced for quick sale' today
Kosher dill spears
Black Forest ham. Bacon works, too, but I like ham better
Thinly sliced onion
A bit of freshed cracked black pepper on the beef, little bit of everything on top, roll it up and tie it off. You can use a toothpick, but string works better.
I cook it in the crock pot with some tomato juice and beef soup base sprinkled on top. You could do it in the oven, in a single layer, at about 300° for a few hours, covered.
Serve with spaetzle and kraut.
