My kids love these homemade fruit roll ups more than store bought brands. They take up to 24 hours to dry in a dehydrator, so plan your time accordingly.
Mix applesauce with kool-aid packet.
Spread 1/2" thick on fruit roll sheet in a dehydrator. Dry according to your dehydrator's directions (usually about 24 hours).
When dry, lay on plastic wrap, roll up tightly, and cut with scissors through roll into desired servings.
