Ham and Bean Soup

Hubby and I wanted to try some Ham and Bean soup in the crockpot so we basically made up our own recipe. I put 8 C water in my slowcooker, added 2 C of pinto beans (next time I will add at least 3 maybe 4) We put in the Ham bone with a little meat on it from Christmas and also a whole onion chopped up. Cooked that for several hours and when the beans started to get soft we added salt and pepper, a little thyme and garlic powder, and some more chunks of ham..simmered some more, when beans were mostly done we added 1 28 oz can of whole tomatoes chopped up (we leave big chunks lol)and also a can of tomato paste, turned out really good. We were quite pleased with ourselves :D
I think next time I will add in some chopped celery or carrots too. I think it took about 6-8 hours cant remember exactly
