I was once trekking in northern Thailand with some Akha hill tribe guides. When it was time for dinner, they cut down a large bamboo and within minutes fashioned essentially a complete dinner service out of it:
* A framework for their overnight hut/lean-to
* A pot for boiling rice
* A frame to hold the pot over an open fire
* Bowls for serving and eating

(...and obviously the darker pieces of bamboo were reused from previous camps.)
