Brown 1 lb ground pork, & remove from pan. Dice a small onion and a few garlic cloves (or scapes!) and cook in the pan drippings until soft. Slice a few mushrooms (shiitakes are especially nice) and scallions. Chop finely the rest of the cabbage. Mix it all together. Add a glug of sesame oil and soy sauce. Chinese rice wine or hoisin sauce would also be good additions.
Place a scoop of filling on each leaf, fold in two sides, then roll up. Can be eaten room temp or put in a covered casserole dish and warmed in a 350º oven for 10 minutes or so.
