A suggestion for non-fussy cooks: You might think this sounds really delicious, but that there's no way you'd steam a whole head of cabbage, never mind rolling the filling into the leaves! If these flavors sound delicious to you, I recommend cutting some cabbage into shreds and sauteing it with the sausage, leek, carrots, and garlic, then deglaze the skillet with the white wine, sprinkle the basil over, and eat it just like that. This makes it a one-skillet dinner! It would be delicious with rice and don't forget the Parmesan cheese!
