Have you thought about tin pie plates? I have eaten off of them in BBQ joints before.
Also there is a restaurant at Lake of the Ozarks that serves all kid meals on a frisbee. Another one serves kids meals like fries, chicken strips, mini corn-dogs in a small plastic bucket w/shovel
something like this, but they were a little more rustic.
