is a pretty good source for a variety of lightweight recipes. We took a lot of ideas from that site on our 7 day Alaska hike. We got our food down to 12-14 lbs per person for the entire trip, including snacks. Everything was cooked by boiling water and pouring it into the freezer bag with the meal, and letting it sit. It worked well, and made cleanup easy (no dirty pots). Don't bother with the bag coozies that the site talks about, you don't need them. Usually if it was cold out, we would put all 4 bags together inside a camp towel to help them stay warm, but I don't see the need to bring the extra weight of any specific bag insulator. Instant oatmeal or cream of wheat for breakfast every day, lunch was often peanut butter/honey/raisin wraps (soft tortilla wraps store well in bearvaults, but tend to stick together), or tacos (wraps, refried bean mix, cheese, diced onion). Since we were in colder weather, the cheese block was fine for the trip. Fresh diced onion makes a huge difference when you're out hiking, and it keeps well. Dinner we had spaghetti (noodles, dried veggies, and made a "leather" out of the sauce), and various other noodle-based meals, couscous works extremely well, as it soaks up a lot of water and is very filling, if you have some sauce mix to throw in before you pour the water in, the noodles soak up the flavor (like soy sauce packets).
Using meals like that, we managed 23 meals and 25 snacks per person, in 12-14 lbs. Most meals were prepared individually, but a few were 1 community bag that the 4 of us shared eating out of. The portions of the meals were slightly smaller than I might have liked, but having 3 snacks set aside a day made up for it. Snacks varied from bars, candy bars, cookies, dried fruit, and trail mix. We were well nourished on the trip. The food on this trip was several calibers above our last trip, where we all used the Mountain House freeze dried meals (yuck) from REI. This was a *lot* cheaper as well, although more setup effort in drying the food and preparing all the bagging.
The only downside to it, is you need to have water available for each meal, so a lot of the meals we had wouldn't work for backpacking in areas with little water.
