For instance, every time I make meatloaf, I grate in four or five carrots and add oatmeal. My meatloaf is deeeelicious!! That's just one off the top.
Give the kids a list of healthy foods and have them vote. Then!! It'd take a professional chef three days to put together some healthful and restaurant-worthy dishes with these ingredients.
I like your idea. First let the kids vote. Then have a chef put together those healthful recipes. Then have the kids vote on them as school days pass.
