If you wanted you could pre-pack single serving meals in ziplock bags using instant rice and dehydrated vegetables. In camp you just add boiling water, vegetable oil, and canned chicken/tuna and let it sit in the freezerbag for 5 minutes of so. You can also do the same thing for breakfast by packing oatmeal, rasins, nuts, etc. into a ziplock, and adding powdered milk and boiling water. Here's a good site mentioned here before that has great ziplock bag recipies.
