Wash the apples thoroughly under cool running water and slice each apple horizontally into half-inch thick rounds, removing the core.

Spread a generous layer of Greek yogurt on one side of an apple slice using a spatula or the back of a spoon.

Sprinkle the granola over the yogurt-covered apple slice evenly.

Drizzle honey or maple syrup over the granola for added sweetness.

Place another apple slice on top of the first, yogurt and granola side facing down. Press down gently.

Serve immediately for best freshness and crunch.
