Slit through the skin of each banana and slightly into the banana itself, along the length. Break the chocolate into pieces and divide across the bananas, poking bits into each slit.

Put each banana onto a sheet of foil, slit facing upwards, and crunch the foil edges together around the bananas to create parcels.

Carefully place the parcels int the barbecue embers for about 15 minutes. Remove with tongs, open with care, transfer to plates and enjoy! Best served with vanilla ice cream.
