Put the yogurt chips in a microwave-safe bowl and heat in 30-second intervals, stirring between each, until melted. Combine the sesame seeds and ground ginger in a shallow dish. Dip each caramel apple in the melted yogurt mixture then roll in the sesame seeds. Let stand on parchment paper until set. If you like, place each caramel apple in a jumbo muffin liner and package in a clear gusseted treat bag. Tie with festive ribbon.
