Backcountry Eats by Kevin Ride ©2021 (eG-friendly Amazon.com link) follows a guy (and some friends) who do a lot of hiking, backpacking, canoeing and camping who was/were desirous of better food than can usually be purchased ready-made. All the recipes are first made at home and then dehydrated so they are light and non-perishable. Most of the recipes are accomplished by covering the food with water, bringing to boil, and then resting for 10-15 minutes.
While it's opposite what most folk on this thread might use dehydrators for (Mr. Ride dehydrates frozen vegetables, cooked rice and beans), there's a lot of generally useful information about dehydrating and rehydrating food.
And I read every single one of the 100+ recipes!
