Follow these steps to create your Mediterranean Chicken effortlessly:

1. Marinate the Chicken: In a bowl, combine olive oil, garlic, oregano, thyme, paprika, salt, and pepper. Add the chicken breasts to the marinade and let it sit for 15-30 minutes.
2. Preheat the Oven: Preheat your oven to 375°F (190°C).
3. Prepare Vegetables: While the chicken is marinating, slice the cherry tomatoes and red onion, and dice the cucumber. Set aside.
4. Sear the Chicken: Heat a large oven-safe skillet over medium-high heat. Once hot, add the marinated chicken and sear for about 4-5 minutes on each side, until golden brown.
5. Add Tomatoes and Onions: Gently nestle the halved cherry tomatoes and sliced red onions around the chicken in the skillet.
6. Bake: Transfer the skillet to the preheated oven. Bake for 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
7. Prepare the Dressing: While the chicken is baking, mix together the lemon juice and chopped parsley in a small bowl.
8. Plate the Dish: Once the chicken is cooked, remove it from the oven. Allow it to rest for a few minutes. Serve the chicken topped with the roasted tomatoes and onions, cucumber, and a drizzle of dressing.
9. Garnish: For an extra touch, sprinkle with feta cheese if desired before serving.
