Heat a griddle or frying pan and bake your chicken. Be careful as the harissa tends to spatter a bit
Put a pot of boiling water on and add 1 cube of chicken stock. Once boiling add your quinoa and cook for about 15minutes or according to package instructions.

Roast your sunflower seeds in another (dry) pan
Drain the quinoa once cooked and add the baked courgette and mushrooms to it. Be sure to check the seasoning and add salt and pepper where needed. Add the sunflower seeds. Slice your chicken and drape over the quinoa. Sprinkle with chives.
