On food you often get a glammed up picture of the food inside with the text serving suggestion alongside it. It tells us that what we can expect in the box is probably nothing like the picture. Create a piece of art around the theme of serving suggestions. Either taking exsisting boxes and making them more honest or real things in the world and adding the words "serving Suggestions" to indicate that all is not quite as it seems. You can buy really great see through sticker paper which goes on windows and can add your text to the view from a bus or car.
