Red Cabbage

We harvested the last red cabbage from the winter planting.  It weighed 7 lbs after the large outer leaves were removed!  Wow! That's the largest one I've ever grown.  Now, what to do with the red cabbage: sweet and sour cabbage?  cabbage slaw, again?  It does seem that although the red cabbages are prettier in the garden they are not as versatile as green cabbages. I don't think they make sauerkraut out of red cabbage, do they?
