A number of years ago, an acquaintance of mine belonged to a dinner co-op. The concept was simple: four friends (living on the same block) shared the burden of the evening meal. Each friend was assigned one day of the week (Monday through Friday) and on her assigned day, cooked dinner for all four families. The other three days, she sat back and waited for her family’s meal to be delivered.

At the time, I thought it sounded like a convenient idea–even an ingenious idea–but I didn’t consider it to be necessarily a ‘green’ idea. I realize now I was wrong: dinner co-ops are a great way to be environmentally responsible while enjoying the awesome benefit of cooking only once or twice a week.
