I really like the Enertia Trail Foods line.  They are dehydrated, not freeze dried.  They prepare easily and most can be done right in the pouch.  Plus, they are single serving sizes and take very little space.  They have entrees and desserts.

If you look around, you can usually find their sample pack on sale at one website or another.  Then you get a variety of meals to try, at a substantial discount.

Several of them are vegetarian, so I often bring dehydrated venison or chicken to add some meat and calories.
