Arrange two squares of heavy duty aluminum foil on a baking sheet. Arrange one sliced apple on each sheet; sprinkle each with half of the coconut sugar and cinnamon and a pinch of salt. Add 1 teaspoon ghee and half the granola to each packet, then fold over the sides of the foil to seal the apples inside.
Grill on high, seam-side up, for 12-15 minutes, or until the apples are tender.
