Can't find the exact recipe, but I remember they had meat, pork and added cooked rice to it. I did find this at the google recipe group:
I watched an episode of Diner's Drive-Ins and Dives this week and Guy
went to Kramarczuk's in Minneapolis. One of the dishes they made for
the show was their cabbage rolls....Holubets....
They lined the pan with whole leaves, then put the rolls in, poured
the sauce over and then covered the whole thing with more leaves.
Their cabbage rolls looked really good and HUGE.
