Marinate the chicken in 1 tablespoon of the olive oil and season with the paprika, garlic powder, salt & pepper.
Heat a large skillet on medium heat then drizzle in another 1 tablespoon 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 sliced 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 broth and mix together.
Place the chicken back into the couscous. Cover and cook on low for about 20-25 minutes. Uncover and garnish with fresh chopped parsley and lemon slices.
