Peel the pineapple, remove the core and cut into chunks. Halve the nectarines or peaches, remove the stones and cut into thick wedges. Cut the kiwi into quarters or sixths (depending on size). Toss all the fruit together in a bowl with the sugar. Turn into a shallow foil tray.
For the sauce, put the Dr. Oetker Chocolate Chips into a small bowl with the single cream. Place over a pan of simmering water and stir until completely melted and smooth. Remove from the heat and allow to cool.
Place the foil tray on the rack of a pre-heated barbecue for about 8-10 minutes until the outside begins to caramelize and the fruit is warmed through.
Stir the Dr. Oetker Mini Mini Marshmallows into the chocolate sauce and serve in a bowl with the grilled fruit.
Tip: If your BBQ is just for grown-ups, pour some rum over your fruit to marinade it whilst cooking to give your dessert a bit of a kick
