Place a pizza stone on a covered BBQ grill, such as the 15” Broil King Grilling Stone. Close hood of the BBQ and preheat on high for 15 minutes.
Lay the pizza base on the preheated grill stone and cook until it turns a golden colour. Flip the pizza base and heat on the other side until golden.
Once both sides of the pizza base have bronzed, spread the Nutella or your favourite nutty cacao spread over the pizza base to completely cover. Sprinkle on the ricotta, crushed pistachios and marshmallows.
Close the BBQ hood and cook for 2-5 minutes, or until the marshmallows have melted and browned to your liking. Transfer the pizza to a cutting board.
Sprinkle over the fresh strawberries and dust with icing sugar. Cut the pizza and serve. Enjoy!
