Place the sugar in a large bowl, then add the fruit and toss gently to coat.
Preheat a griddle pan until hot, then add the peaches, cut side down, and griddle over a medium heat for 2–3 minutes until caramelized, then add the apricots. Turn over the peaches and cook for a further 2–3 minutes or until the apricots and peaches are soft.
Meanwhile, place the yogurt in a bowl and pour over the honey. Stir to create a rippled effect. Serve the warmed griddled fruit with the honey yogurt.
