Heat a gas or charcoal grill. Cut peaches in half and remove pits. With a melon baller, scoop out a little flesh to enlarge the cavity where the pit was removed. Brush peaches lightly with olive oil on both sides. Place peaches on grill, cut side down. Grill about 2 minutes or until grill marks form. Turn over and grill for 2 minutes more. Place peaches on a serving platter, cut side up. Fill holes where pit was removed with Kerrygold Cashel Blue Cheese and drizzle peaches with honey. Serve warm.
