01 - Preheat the oven to 400°F (200°C).
02 - In a large bowl, whisk together the lemon juice, lemon zest, minced garlic, dried oregano, dried thyme, salt, pepper, and olive oil until well combined.
03 - Add the chicken breasts to the marinade, turning to coat evenly on all sides. Allow to marinate for at least 10 minutes at room temperature, or cover and refrigerate for up to 2 hours for deeper flavor.
04 - Transfer the marinated chicken breasts to a baking dish. Scatter the halved cherry tomatoes and sliced olives around the chicken, then pour any remaining marinade over the top.
05 - Bake for 25 to 30 minutes, or until the chicken is cooked through and the juices run clear. The internal temperature should reach 165°F (74°C) when checked with a meat thermometer.
06 - Sprinkle the crumbled feta evenly over the chicken breasts and return to the oven for an additional 5 minutes, until the feta softens and begins to lightly brown.
07 - Remove from the oven, garnish with fresh chopped parsley, and serve with lemon wedges on the side.
