You bet we do. We don't recommend mess kits per se, but a kit of stuff purpose bought and stored in a gallon sized freezer bag.  A metal plate; aluminum, stainless or titanium, whichever they can afford, a plastic cup, a metal bowl for boiling water and eating out of, a long handled metal spoon, pot holder and small green scrub pad.  Use it for plop camping and hiking.  It will last a lifetime, for just a few dollars more.
