we mostly do fruits...the kids love to snack on them.
our favorite recipe is to slice apples into "moon shapes" and shake sugar and cinnamon on them, then dehydrate. The first batch is usually eaten warm...then, I get to store some =).
We also love to do strawberries.
so far cantaloupe and watermelon have not been a big hit here.
and, yes, jerky is fun.
I am considering trying to dehydrate spaghetti sauce.
