We did this
here a short time ago and there are plenty of opinions.
Mine have changed since then. Inertia meals were a favorite of mine for a while but I think they may have changed the formula as the sauce in the last 3 or 4 has not been as good and did not re-hydrate as well.
I'm back to dehydrating my own meals for dinners.
For lunch I still like pre-packaged tuna or chicken with a little mayo packet in a pita bread.
For snacks I picked something up a few weeks ago from Little Sister: Sliced green and red peppers, carrots, and celery with hummus.
I'm still taking standard Cliff bars and gu. Oh and peanut butter on crackers.
