Preheat a Belgian waffle iron.Place a large skillet over medium heat and add in the olive oil. Once oil heats, add in the sweet potatoes and season with salt and cinnamon. Toss and cook for about 10 minutes or until noodles are cooked through. You can cover to cook more quickly.Transfer the noodles to a large mixing bowl and add in the egg and chocolate. Toss to combine.Spray the preheated waffle iron with cooking spray and pack in the noodles carefully. You may have to play around with the noodles to get them to fit in all of the grooves.Cook the waffle according to your iron’s settings.When done, carefully remove the waffles and transfer to plates. Top with any toppings you’d like, but don’t forget the maple syrup.
