You think a “socially minded” health food store or co-ops may donate some ingredients or other items for a cooking or food prep class? Simple and fun recipes with a small curriculum might be an enjoyable prospect for some people in your program. You don’t even have to do cooking if the center is concerned about that. You are much more than aware that the average person of recipes that are healthy and relatively simple to make. Social skills, lifeskills, community involvement, healthy living. Might make a good mix.
