I guess I should have clarified what you cook to include how you cook it.
I don't see how anyone can do stir fry, pies, cakes, etc. with a white gas stove or any other portable stove. I don't have room for a dutch oven, so I don't know how these got made.
As for me, if I did marinara sauce from a jar and pasta, I would be in trouble because there is not enough protein in it to sustain me.
Beans and rice from a bag are OK, but it does use a lot of fuel to cook, and I don't advise riding behind me the next day.
On my last weekend trip, my touring partner and I were each responsible for one dinner. He boiled instant brown rice, with canned chicken, and canned black beans. Very filling, although the chicken has a funky smell to it (taste is OK). I boiled canned ham with instant rice-a-roni. Actually, I attempted to saute the ham with a little olive oil before adding the water, rice, and seasoning packet. Also very tasty, no funky smell, ham has a funky texture. We both used white gas stoves.
