Here is the thing that comes to my mind on this issue. For the same 6 pounds you could probably carry two (or maybe even three) cartridge stoves with a fuel canister for each along with a couple pots with lids, a reasonable saute pan, a lightweight reflector oven, a 9"x9" pan for the reflector oven, and some other stuff of your choice. You could prepare some pretty elaborate meals with a setup like that.

BTW, here is one example of a 9 ounce reflector oven. I have one that weighs a bit more but is able to handle larger pans. I have fixed some really yummy baked stuff on canoe trips, but like to keep it light and simple on bike trips so it stays home.

All that said, I'll stick with a single light weight pot with a frypan lid.
