I carry a cup that nests over a Nalgene bottle and a coleman Peak 1 butane stove. I also carry a cheap cafeteria style steel teaspoon. Mostly, I make hot chocolate for a pick me up, but I also carry Campbell's instant soup packets and salt. I don't think there are too many things I'll catch that I can't chop up and make some sort stew out of.

I'm also considering adding a Squishy bowl to my army kit, since the move to camelbaks instead of canteens means no more steel canteen cup. The Squishy bowl can't do everything that a metal cup can. But its super light and will squish into a tiny space in my camelbak. So I at least have some option for cooking or boiling water.
