Chinette paper plates and into the fire afterwards. Almost nothing for weight or bulk to carry along and animals won't dig it up later (and yes, they WILL dig it up and eat it!).

Also, a firm grip on something helps ensure unexpected recoil doesn't cause you to lose balance and become collateral damage. Been there.
