If the food is not edible the facility should be reported to the proper authority. The idea is commendable. Can the elderly you are serving afford what you propose? Will the facility allow "catered food" delivered to the residents? It does sound something like meals on wheels. I am of an age where many friends have been inmates in long and short term care facilities. Many of them did not care about healthy food. One disabled friend has started smoking again because she wants to enjoy her last days. I know this sounds cynical but who really wants to play bingo and do crafts while giving all their children's inheritance to the medical profession? Welcome to Chef Talk. If you do decide to get started this community will do all they can to help. Replace cynicism with humor, I'm not sure you can cook good southern food without pork fat.
