Preheat the oven or air fryer to 200 C / 400 F.
In a small bowl, add chicken pieces, olive oil, spices, salt and pepper. Mix well.
Spread the chicken pieces on a baking sheet with parchment paper for the oven OR on on a paper lining for the air fryer basket.
Bake the chicken for 15 minutes or until it reaches an internal temperature of 75 degrees C (165 degrees F). If using the air fryer, check in after 10 minutes it may only need another 2-3 minutes instead of 5.
Let the chicken cook and rest for 10 minutes before slicing into it and carving.
Meanwhile, in a bowl, add the couscous and kettle boiled water. Cover immediately with cling wrap and allow to steam for 5 minutes.
After 5 minutes, once the water has all evaporated, remove the cling wrap and fluff the couscous with a fork and set aside to cool.
In a large bowl add the cooked couscous, and all the salad veggie ingredients - red bell pepper, cucumber, cherry tomatoes and red onion. Mix well.
Add the cooked and cooled chicken and mix again. Pour the red pepper dressing over, mix and taste for seasoning. Add the chopped parsley if preferred and serve.
