This thread hasn't been active for a little bit, and I recently put together a mess kit system that is working pretty well, so I figured it might be a good time to bring it back to life.
I'm using a German mess kit (thanks Housil!

), and found that the inside has plenty of room to hold all of the essentials. When camping, I take it along with my US canteen, which I've replaced with the Nalgene version that doesn't leak, but is a drop-in replacement for the US issue canteen. With the canteen cup and stove that are a part of that, these two items are usually all that I need.

Inside the mess kit, I am able to fit all of these items:

The Trangia alcohol stove as well as the Esbit solid fuel stove fit perfectly down inside the pot, and in the inner "bowl" that fits inside, I have a small mesh bag that contains a few packs of matches, extra alcohol fuel, an eating device, titanium pot / cup holder that goes on top of the Trangia, and trash bags.
The titanium pot / cup holder that fits on the Trangia is awesome! It weighs next to nothing, stows easily, and works great for it's intended purpose. I highly recommend.

I just thought I'd share my setup. I got the idea from seeing the great ideas that many of you already posted. I've finally got a mess kit setup that I'm happy with.
Thanks for reading!
