01 - Place chopped apples, cucumber, lemon juice, and grated ginger in a blender. Process until completely smooth, approximately 1-2 minutes.
02 - Add Greek yogurt, apple juice, cold water, honey, salt, and black pepper to the blender. Blend until fully incorporated and creamy, about 30 seconds.
03 - Taste the soup and modify seasoning or sweetness as needed. Add more honey for additional sweetness or more lemon juice for brightness if desired.
04 - Transfer the soup to a bowl, cover tightly, and refrigerate for a minimum of 1 hour until thoroughly chilled. The soup can be made ahead and stored for up to 24 hours.
05 - Stir the chilled soup before serving. Ladle into individual bowls and decorate with fresh mint leaves and thin apple slices.
