Supper Cooking Club

Get a group of friends or strangers together and once a week, in an industrial kitchen, make one meal that could feed everyone present (or maybe everyone and their families?), like lasagna or enchiladas or whatev.  Then divvy up all the foods and put them in containers you reuse each week.  Take the foods home and have a different meal each night.

This works great if you have trouble making food for fewer than 20 people.
