I come from a lightweight backpacking background, meaning we have light backpacking stoves that are great at boiling water and then we just pour it in some dehydrated food like oatmeal, freeze dried stuff, etc. OK for short backpacking trips. Crappy for long trips. Sometimes you just want to buy some raw ingredients from the grocery and have a real (and cheap) meal. Since a RTW trip is going to be very, very long, I'm looking for some cooking options that will allow me to make real foods with raw meats and stuff. Even stews. Preferably one that doesn't require me to make an actual fire every night. Any ideas?
