雪菜 xuě cài, meaning 'snow greens' is salt fermented, chopped mustard greens. These I bought from the supermarket, but I have made them myself from time to time. The ones on the plate below are home made. The next image is the supermarket variety.
Anyway, I had some in the fridge. Usually they are cooked with slivers of pork and chilli, but I was out of pork and too busy to go get any. A rummage in the freezer produced a pork kidney, the nearest I was going to get. So I cleaned and sliced it., marinated it in Shaoxing wine with garlic, ginger and chilli, then stir fried it with the snow veg and finally some green onion..
Served with rice.
I've never seen or heard of kidney with snow greens before, but I'd make it again.
