Preheat oven to 400F.
Start by preparing the pearled couscous according to package. If using unflavored pearled couscous, I would recommend adding in some seasoning like garlic powder, onion powder and Italian seasoning.
Next, prepare the chicken. Pat the chicken dry with paper towels. Season both sides generously with salt, pepper, paprika, garlic powder, and onion powder.
Heat 1–2 tablespoons of olive oil in a large oven-safe skillet over medium-high heat. Once hot, add the chicken and sear for 3–4 minutes per side, until golden brown.
Transfer the skillet to a preheated oven at 400°F and bake for 12–15 minutes, or until the chicken reaches an internal temperature of 165°F.
Remove from the oven and let rest for 5 minutes before chopping into bite-sized pieces.
Next prep the veggies. You can either finely chop the bell peppers, cucumbers and red onion with a knife or use a vegetable chopper. Slice the cherry tomatoes in half and finely chop the fresh parsley.
Add all ingredients, including the pearled couscous and chicken to a large mixing bowl.
Next, prepare the dressing by whisking all ingredients together in a small bowl. Pour dressing over salad and mix well.
Serve salad immediately at room temperature, or chill in the fridge for an hour or more.
