Add sugar and cinnamon, and saute for 1 more minute.
Transfer apples to a plate to cool, about 10 minutes.
Place 1/2 cup yogurt in the bottom of a wine or martini glass. Repeat with second glass.
Place 1/4 of apples in each glass.
Add 1/2 cup yogurt to each glass.
Top with remaining apples.
Notes
This dessert is best served immediately or within the hour to keep the apples crisp.
I used Honey Crisp for this recipe; use which apples you like best.
