My lightest cookset is a Snow Peak Trek 700 titanium pot, and an Antigravity Gear food cozy. I boil water in my pot, pour it into the dried food in a heavy-duty freezer bag (though, as pointed out elsewhere, Mouse prefers dried foot), and place the bag in the cozy to rehydrate. Food is oatmeal in the morning, and some kind of rice-and-meat dish in the evening. I prefer the bags my outfitter sells, which are the same kind Enertia uses to package its food; no worries about holes or hot water melting them.

If I want a cup of hot tea, I make it in the pot (depending on how much water the food takes, that may mean a second fill-and-boil, or just using what's left from the first boil.)

If, for some reason, I don't want to use the freezer bags (such as, I get tired of getting food all over my fingers dipping my spoon into the bag), I take the Jetboil Sol kit, and cook in the pot or make oatmeal in the little measuring cup. Hot tea has to wait till I'm done eating, though.

Lately, the 700 pot and food cozy seem to be going most often.
