We haven't done this at school but we did recently do this at church. We used Cookbook Publishers Inc. If you call them, they will send you an instruction kit for free. 800-227-7282 24hr #.
We had one chair at church and she utilized e-mail, flyers and at our monthly enrichment nights, she "harassed" [img]smile.gif[/img] us.
It turned out really well but I don't know how much money was made. We paid $6 for the cookbook and it is well used in my kitchen!
