Have you ever participated in a long-term meal sharing arrangement?

I’ve read about families in neighborhoods or in cooperative living arrangements sharing the workload of grocery shopping and preparing meals by having each family in the group cook one big meal per week with enough portions to share, than swapping the spare portions with the other families in the group. Have you ever done this or something similar to this? How did it work out? What were the pros and cons? What worked? What didn’t work?
