This is based on a recipe from Lydie Marshall's cookbook, Slow-Cooked Comfort. She says of this recipe, "When I have leftover meat from a stew, I grind it and freeze it.... With ground pork, I make a pork and cabbage lasagna: layers of ground meat and cabbage leaves with a white sauce on top. Because the pork is already cooked, this is a relatively quick dish to prepare." I think this is a good cross between lasagne and cabbage rolls with a very appetizing appearance. This dish can be prepared several hours ahead of time before being placed in the oven.
