I've made something similar to this before but we liked this so much better. The smoothness of the broth was great. I used chicken stock and didn't use celery. I made it in the crockpot, loading everything and then just turned it on high until it was done, about 3-4 hours. I scooped out the meat and veggies then added the flour mixture. We will be making this again as we have tons of green beans.
Delicious and a great way to use a ham bone!
