This is the setup that I use, because my buddies are too cheap to buy their own gear, so this is for my "family" of 3.
With the exception of the weight of the condiments (white dropper bottle) everything fits inside the pot, and weighs 24.6 oz in a packed size of 6" tall x 5.5" wide.
The reflectix cozies are extremely effective and weigh next to nothing.
However, I'm likely going to try to use Freezer Bags and a reflectix envelope/cozies next time I go out. Simply because washing dishes is a pain, especially in bear country (because I am paranoid).
In this case all you would need is the smaller pot. The Snowpeak 900 and this weighs in at 16.4 oz. total, packed 5"tall x 4.75" wide. I can now also have tea with the extra water while my food is hydrating. Pot makes a great mug.
Dehydrating is definitely the way to go. Very very easy, light and inexpensive (my post on stew/dehydrating is down the page):
The pots are a Snowpeak 900 & 1400. I got them from O2 gear shop for $65 (found deal on Amazon).
The stove is a Coleman F1 Ultralight ($35 Amazon). I like that it breaks down into 2 pieces for better fit. The thing is a flame thrower. If I had to choose another, I'd likely go with the Snowpeak Giga Power.
There is probably lighter, and this or that, and I honestly haven't tried "all" the options, but in my opinion, why bother. This is easy, inexpensive, reliable and clean for 90% of the trips I do. I don't want sooty pots in my pack, look for dry twigs, etc.
If I was going solo or with a partner who wanted to tinker, then I might explore other options. Chances are though, I'd go back to this setup for the convenience.
I cooked a couple of eggs in the frypan lid of the 1400. It worked, and tasted fine, but was a pain because some of it burned and had to scrub to clean lid. I did this only once in my kitchen. I'd likely get better with heat control with experience (take pan off and on stove, moving pan around flame) and was thinking of trout...as soon as i figure out how to catch them. Point is, it can be done.
BTW that canister is the 225g/8oz large one. I"m surprised at how long it lasts. And sometimes you hear people say, the alcohol is cheaper etc... but it's $6 and will likely last you guys a week if not more if all you're doing is boiling a liter or two of water twice a day (I'm guessing here).
Hope this helps.
