I used 2 small organic garnet yams and sliced them into 'coins'.
This filled 3½ trays in my dehydrator. I set it for 135ºF and dried them overnight. Turned out nice and crunchy! You could sprinkle them with various herbs before drying, but they are tasty by themselves. You could also use them with your favorite dip. I like them, as do my dog and bunny!
The dried chips filled a 1-pint jar.
