Second, how large is the work group and is it stable, or does the membership change every week?

Third, do you have an institutional serving line, or is it serving from a table?

Also, find out how others are doing it. With this time limit, they may be bringing in all the food already prepared. What menus? Cold foods? Hot foods?

I always include a cut up fruit dish and a dairy dish for homeless cooking; vitamins and calcium are in very short supply on the street. Also some good large cookies or bars that can be taken away.

Teeth are bad, meats should be tender-cooked. One reason why cold cuts/ sandwiches are popular.
