Prepare the Grill:
Preheat grill to medium-high heat. Clean grates thoroughly.
Prep the Peaches:
Wash peaches and cut each in half, removing the pit.
Brush the cut side of each peach half lightly with coconut oil.
Grill:
Place peaches cut-side down on the hot grill.
Grill for 4–5 minutes, until grill marks appear and the peaches are softened and caramelized. For crosshatch marks, rotate peaches 90 degrees halfway through grilling.
Serve:
Remove the peaches from the grill. Serve warm, garnished with fresh mint, a dollop of Greek yogurt, or a drizzle of honey, if desired.
