Pre-heat your grill to a medium heat, or prepare your bbq
Cut the bananas in half lengthways (keep the peel on) and brush the cut side with the melted butter
Place the bananas cut side down onto or under the hot grill, and cook for 3-4 minutes or until you see them grill marks form, keep basting in butter every minute or so to help the bananas caramelise
Use a spatula and tongs to carefully flip them over and grill for another 4-5 minutes covered, until the bananas is really soft and pulling away from the peel - this timing will depend on the size and ripeness of your bananas
While they are cooking, stir the vanilla into the coconut yogurt and set aside
To serve mix the remaining melted butter with brown sugar and cinnamon. Remove the bananas from the grill and baste in the syrup, then serve with a dollop of yoghurt and a sprinkling of the toasted hazelnuts, drizzle of honey and freeze dried raspberries.
