Wash the chicken breast and cut into bitesize cubes. Set aside in a bowl.
Add 3 tbsp of the yoghurt, freshly chopped garlic, red chilly powder (or smoked paprika), cumin powder, sumac, salt and pepper.
Squeeze half a lemon into the bowl as well and mix throughly until each cube of chicken is marinated.
Cover with some cling film and leave to marinate for 25 mins. (You may even do this the day before and leave in the fridge overnight)
While the chicken is marinating, place the uncooked couscous into a separate bowl and add the boiling water to hydrate it.
Cover with a lid/plate and leave for 5 minutes or until the couscous is fluffy and cooked.
In the meantime, finely chop the red onion, green chillies as well as the cucumbers (scoop out the seeds with a spoon to avoid a watery final product) into little pieces.
Once the couscous is cooked, fluff up with a fork and add the onions, green chillies and cucumbers. Mix carefully.
Now add salt and pepper and taste to see if you need to temper the seasonings.
Pour oil into a shallow frying pan on high heat.
Once the pan is hot, carefully add in the marinated chicken cubes and spread out to ensure they brown nicely.
Though chicken cooks very quickly, fry on high for 5-7 minutes or until the outside is a golden brown color.
Drain any excess oil once the chicken is cooked through, using a paper towel.
Now prepare the dressing by combing the rest of the yoghurt, mayo, the juice from half a lemon, garlic powder, salt, pepper and dried parsley. Mix well and if the dressing is too thick, add water, teaspoon by teaspoon until the dressing reaches a pourable consistency.
Now all three components are ready, you can plate! Spoon out the couscous on a dish and place the chicken cubes next to or on top of it. Drizzle over the dressing and you may even add some chilly sauce for that extra kick!
Enjoy!
