Start your braai until you have medium heat coals.
On a flat surface, layer the tennis biscuits and spread a teaspoon of Nutella spread onto one biscuit.
Carefully pierce the marshmallows using your Kebab Grill Set and roast them on the braai until they have a golden tan colour.
Place the roasted marshmallow onto the Nutella spread biscuit, drizzle over melted dark chocolate and sandwich together with the top tennis biscuit. Repeat with the remaining biscuits.
Serve immediately and enjoy with a glass of milk at your campfire!
