A week long trip doing what? Long hike, pickup camping, water source? I dehydrate most of my meals, but when I am close to the truck, which I do a lot of these days, I carry different stuff.
+1 on Zatarains with a foil pack of chicken, it's pretty good in a pinch. It's not light, but whenever I go with one group of friends, we always bring a can of corned beef hash. It's more of a tradition than reasonable packing. That stuff is pure sodium/fat.
Dehydrate if you want to save money. Eating freeze dried is the same cost of eating at a restaurant every day. You can do less than 5.00/day is you plan a menu.
I start my dinners menu with a starch base of pasta, or minute rice, or instant potatoes. Then add dehydrated veggies, then a protein - freeze dried meats or cut up hard sausage, or foil/tin of chicken/fish. Add a dehydrated sauce or packaged gravy to round it out. Condiments on the side -usually tabasco.
Dinner Favorites - shepherds pie, mac and cheese with curry and tuna, rice with knorr hunter sauce and chopped up chorizo/landjaeger sausage.
Lunches - pita, salami and cheese or nut butter and jam
Breakfast - instant oatmeal and coffee. Makes for a regular hiker

I dehydrate my own meals. The sodium in the freeze dried food was just way to excessive for me. Freezer Bag Cooking has tons of good recipes and I rehydrate my meals in one of Sara's cozies.
Lots of good input on this thread. FYI, I have had this dehydrator for 2 years now and it works well. It has gone up in price, but for my use it has worked well. It has a variable temp control and comes with 5 trays and 2 different types of "fine food liners".
