Dehydrated Meals for 72-Hour Kits?

The Mountain House brand freeze-dried meals the guys took on the Havasupai trip taste pretty good, but they are probably not a good idea for your three day kits.  Each pouch is dinner for two and requires two cups of boiling water.  It would be hard for children and older folk to carry the necessary amount of water for the meals and for drinking.  This product may be an option for one or two meals.  The dinners are very high in sodium (900 mg for one serving of Potatoes & Beef with Onions).  A 2-serving pouch cost about $6.
