Food should be in small pieces before dehydrating, and yep, chicken does best if it's pressure cooked...

But a whole tuna casserole comes back like magic... even the little broccoli trees looked like broccoli, tasted like broccoli.... it pays to set up the dehydrator in a corner out of the way and use it to "store" leftovers, as long as you're going to be using the meals within a month or so. Some things don't completely dehydrate but will definitely be trail worthy. Spread the dish thin as you can on a tray or parchment paper and go.
