This was a common meal in German blue collar working class families. It is still very popular on buffets, and even used to become "hip" recently for people who got bored with mussels, salmon or caviar on buffets. People in old times often did not use ground meat, but ground cheap meat leftovers. This used to be pub food in the very old times in Germany as you could store it for a long time - no fridge was around at that time, only a pantry. It is perfect as a cold snack for long road trips.
"Kohlrouladen" used to be a staple on the menu for regular people in Germany during winter time. The relatively long preparation and cooking time pays out, because it can be easily reheated over a couple of days and gets even better and tastier then. Fried potatoes complete the picture, but you can cook the potatoes also in the pot with the sauce, if there is space left. This recipe can be varied in many ways, be it the stuffing (ground meat here), or the sauce. The recipe is as traditional as it can be; the ingredients are adjusted to availability in North America (like Savoy cabbage in lieu of "Weisskohl", bacon to replace "Speckwuerfel"). For sure the ground meat can vary depending on preferences or diets - I bet quite often in the "good old times " regular people did not exactly know what's in the ground meat they got from the butcher - at least it was some meat, for most of the families only once a week.
