In a large bowl, add 5-Spice Seasoning, peaches, sugar, and olive oil. Toss until peaches are coated evenly.
Place peaches on the grill, flesh side down, for about 3 to 5 minutes. Turn over and grill for about 1 minute. Peaches should have grill marks, but still slightly firm to hold shape.
Remove peaches from grill and enjoy!
