Ditto to what Choc recommends. Though are you in a bind for time? It will take a long time to cook down. Don't forget when you are done try eating it w/ a splash of balsamic vinegar. My friend does that and man is it good!
On a side note, I when I cook greens, I don't get to cook them down to soul food style these days.
My stepson can't handle "mushy" food, so I just cook it only for about 20 minutes w/ some ham or bacon, garlic, splash of oil & broth. - Choc, don't laugh at how I make them now. It's the only way I can get that boy to eat it w/o sitting at the table for an hour.
