Creating Greek Chicken with Lemon and Feta is straightforward. Follow these step-by-step instructions for a delicious outcome:

1. Marinate the Chicken: In a bowl, whisk together olive oil, lemon juice, dried oregano, minced garlic, salt, and pepper. Add the chicken breasts, ensuring they are well coated. Allow to marinate for at least 30 minutes (or up to 2 hours for more flavor).

2. Preheat the Oven: Preheat your oven to 400°F (200°C) while the chicken is marinating.

3. Prepare the Baking Dish: Grease a baking dish with a little olive oil to prevent sticking.

4. Add Chicken to the Dish: Remove the chicken from the marinade and place it in the prepared baking dish. Pour any remaining marinade over the chicken.

5. Arrange the Tomatoes: Scatter the halved cherry tomatoes around the chicken in the baking dish.

6. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).

7. Add Feta Cheese: In the last 5 minutes of baking, sprinkle the crumbled feta cheese over the chicken and tomatoes. Return to the oven until the feta is slightly melted and golden.
