I have not been much of a fan of fruit since I was a kid, but I do love grilled fruit for dessert or even as a side dish. Grilled Pineapple is the best thing with grilled Swordfish.
Most kinds of fruit can be grilled (apples and pears take longer than most). In Italy, fresh or grilled fruit is the usual dessert. (Gelato is not dessert - it's a street snack.)
No need for a recipe, but you can sprinkle some sugar on the fruit while on the grill.
