I fix beans and ham fairly often. I would say with yours, to put them in a large pan, be sure there is plenty of water on them, or your sauce you mentioned, and let them cook oh "med.high-high." This will get the temp. up and they should cook for about 2-3 hrs. and be cooked.
I would check them fairly often to be sure they are cooking okay.
Good luck!
