I saw something where they had a cafe that they trained people to be prep chefs and things like that. You could use that idea, but show kids how to make simple healthy meals. You could have real chefs volunteer or just have good home cooks do the teaching. Have kids take a week at a time helping/learning and serving. You could sell the meal at a cheap price to help bring in some money. Or it could be a free meal, kind of like they would get at school. You might get a grant of some kind for that.
