DS ate a huge mound of red cabbage when we went out for dinner last week. I decided I better buy some (I never buy it usually) as he liked it so much. anyway, boiled some up yesterday, drained added a knob of butter and some black pepper and stirred through on the hob for a few mins. It was quite plain but nice. DS refused to even taste a piece. It looked identical to that he ate in the restaurant so I don't know why he decided not to try it.
I think it would be nice as a spring roll filling (along with bean shoots and shredded carrot) if you like making that sort of thing. Otherwise I'd just serve as a side for something hearty and warm like a stew with dumplings.
