I've done a lot of bike touring and have found a great cook kit that's light and cheap.
I use a 3 quart stainless steel mixing bowl - available at wal-mart for $5. Use a pie pan as the lid. I use an old bike cable as a handle - drilled two holes in the side. The shape of the mixing bowl is great - no corners for food to stick in so clean up is easy.
I use a beer can stove to cook with.

the beer can stoves use alcohol for a fuel. You can use HEET ( gas line antifreeze - yellow container) as a fuel and it's available at most gas station.
When it's nice out I make a tepee with 3ea. 4-5' sticks and hang the cooking pot over a fire. With a slip knot you can raise/lower the pot to be the right height. A small amount of the HEET starts a fire really easy.
Store the cook kit in a plastic bag so the soot doesn't get all over everything. The soot is good - black absorbes heat as opposed to reflecting heat as a polished pot does. And don't forget to take a bit of sandpaper to the bottom of your cook kit - this will rough it up so it doesn't slide off of your stove of choose.
I've used this system for years and it's the best camping pot I've found. I have an arsenal of other cook kits that I spent too much money on....hope this helps.
