Perpetual Stew

The experiment lasted for two weeks and, while there was a ton of flavor, I kept occasionally running into a piece of meat or a veggie that had clearly been sitting in there way too long and it was a huge turn off. Especially the meat. The veggies, if was a potato or a carrot wasn't too bad.
I think if you are continuously going through nearly the whole pot and have a family to feed this could be a great continuous lunch. For someone living on their own and just having it for dinner it got weird.
