Peel the sweet potato and cut into chunks. Boil in a little water until soft, then mash to a smooth consistency. Set aside to cool.
Place the quinoa in a saucepan with the water. Bring to the boil and cook for 15 minutes, then drain and set aside until completely cool.
Place the cooled quinoa, margarine and milk in a blender or food processor and blitz for about 5 minutes, until quite smooth.
Add the cooled sweet potato mash, together with the rest of the ingredients, and mix by hand until well combined.
Spray a 16 x 26-cm lamington tray with olive oil cooking spray.
Pour the brownie mixture into the tray.
Bake in a preheated oven at 180°C for 40 minutes, or until a skewer inserted into the centre comes out clean. Leave the brownies to cool in the tray before cutting into squares.
