Don't Put Purple Cabbage in Cabbage Soup

Hmmmmmm, what  to make for supper?????  Well I have some cabbage in there and some pork ribs.  Probably can find some cannelini  beans in the cabinet.  Hey,  how about a pot of Cabbage Soup.  I haven't made that in a couple of years.  Some carrots and onions and a head of green cabbage and a small head of  (what did I  buy this for?) PURPLE CABBAGE?  So now its in the pot.  And it smells pretty good.  Uh-oh!  Under that lid are some purple beans, purple tomatoes,  purple carrots.......and purple Pork.  I should have known.....but who would have thought......Purple Soup.
