Marinate the chicken in about 1 tbsp of olive oil and season with the paprika, garlic powder, salt & pepper.
Heat a large skillet on medium heat then drizzle in another 1-2 tbsp of olive oil. Sear the chicken on medium/high heat for about 2 minutes per side, until browned. Remove the chicken from the pan and set aside.
To the same pan on medium heat, add in the diced onion and grated carrots. Cook together for 4-5 minutes.
Add in the garlic, couscous and spices. Toss together for 1-2 minutes. Pour in two cups of water or broth and mix together.
Place the chicken back into the couscous and top with chopped parsley. Cover and cook on low for about 20-25 minutes.
