Finely grate (shred) the rind of the orange. Squeeze the juice from the orange into a bowl and blend it with the honey and lemon juice. Stir in most of the grated orange rind and all of the yoghurt. Separate the egg whites from the yolks. Whisk the whites until they are stiff and fold them into the mixture. Spoon this into small glass serving bowls and sprinkle the remaining orange rind over the top and decorate with any other fresh fruit available (like half a strawberry and some bits of melon!).
