Pretty much is as easy as cook, dehydrate with a couple things to remember.
Fat is bad. Use low fat cuts, drain out fat, some places even recommend doing a quick wash of ground meat in a colander. (Fat doesn't keep well and can spoil). You can always bring single serve packets of olive oil and add back in. Dehydrated food won't last as long as freeze-dried, but *should* be good for a year, never tested...
Cut everything small.
Add some bread crumbs to ground meat, helps rehydrating.
You don't want to try to dehydrate something really, really watery or soupy. I took a chili in the crock pot and added a cup of dry / uncooked brown rice and let it sit for the last hour / two to absorb all the water before dehydrating.
I probably over-filled the bags I used below, and ended up eating well.
For adding water, test it beforehand at home so you know how much dry and water so you're not carrying extra.

and these (probably not needed)
Shop FreshUs at the Amazon Storage & Organization store. Free Shipping on eligible items. Everyday low prices, save up to 50%.

I then took an old iron and sealed the mylar bags with the O2 absorber inside so they wouldn't leak
I only tried 3 different recipes last year, need to expand and try more this year.
