Preheat your grill to medium-high heat or prepare a campfire with a grill grate.

In a small bowl, mix the melted butter with 1 tablespoon of honey.

Brush the cut sides of the peaches with the honey-butter mixture.

Place the peaches cut-side down on the grill or grill grate.

Grill for 3-4 minutes, or until grill marks appear and the peaches are slightly softened.

Flip the peaches and grill for an additional 2-3 minutes on the skin side.

While the peaches are grilling, mix the Greek yogurt with the remaining 1 tablespoon of honey and the cinnamon.

Remove the peaches from the grill and let cool for a minute.

Serve the grilled peaches warm, topped with a dollop of the honey-cinnamon yogurt.

Drizzle with extra honey and garnish with fresh mint leaves if desired.
