Preheat grill to medium (375º-425º). Slice peaches into two halves and gently remove pit. Lay all of the halves, flesh side up, on a cutting board or plate. Brush the top side lightly with coconut oil.
Place each half onto grill, flesh side down. Cook 5-6 minutes, until peaches are soft and have good grill marks. Remove from grill.
To serve, place two in a serving bowl, top with a scoop of ice cream, a drizzle of honey and a sprinkle of cinnamon.
