2) Thread one piece of each fruit on each of 6 skewers so that the cut sides line up and lay flat. Sprinkle the sugar over the cut sides of the fruit. Let stand until the sugar dissolves, about 10 minutes.
3) Place the fruit skewers on the griddle cut side down. Griddle the fruit until it is heated through and caramelized, about 5 minutes. Transfer one fruit skewer to each plate and serve.
