Turn on the grill to medium heat.
Cut your peaches in half and remove the pits. You can cut them into smaller slices if you want, just use a grill topper so your peaches don't fall through the cracks.
Place your peach slices/halves into a bowl and drizzle in olive oil, gently stir so that the peaches get covered. You can brush the peaches too (be sure to brush both sides), I just found it easier to put them all in a bowl.
Place the cut side down on the grill and cook until the fruit has grill marks and starts to soften, approx 4 to 5 minutes depending on the size of your peaches.
If needed, turn them once and continue cooking for another 4 to 5 minutes. Do your best to resist moving them any more than necessary so you can get those pretty grill marks.
Enjoy on a salad, with ice cream, with dinner...or just straight off the grill!
