That certainly works. Another option would be to serve it as a dish -> ribs, beans, and greens.
Sounds like the ribs are cooked. Ok, get some pork, veal, or beef stock, maybe one can (serving 2-4) Add a 1/2 can of red wine. Reduce to sauce consistancy.
Were I to do this, I'd reduce the stock with chopped carrots, onion and celery to bump up the flavor and then strain it out. When I have the correct amount of liquid, I then adjust consistancy by adding in a small amount of cornstach mixed with water. The cornstarch will act as a thickener if you give it 2-3 minutes to work. (the strach molecules expand, some of them burst and the enlargened molecules make for a more viscous solution)
