I received this "camping stove" today and it comes with the two pans (they are tiny, like one serving size) and the igniter thing that you screw onto a butane canister (the 4oz ones are smaller and easier to carry). It doesn't come with the fuel, but for around $20 it is pretty affordable.
You probably would need more than one if you are using this for your whole family. But for a bug out bag for emergencies, it isn't too bad at all. super small, easy to pack and carry and lightweight.
You even can hook it up with an adapter, to a larger propane canister, but then you will have to rig the igniter up because it isn't stable just sitting on a rock or flat surface.
Here are some of the features:
