Creating Artichoke & Olive Stuffed Chicken with Oregano Oil is simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Stuffing: In a mixing bowl, combine the chopped artichokes, olives, mozzarella cheese, Parmesan cheese, garlic, and oregano. Mix well and season with salt and pepper to taste.
3. Prepare Chicken Breasts: Place the chicken breasts on a cutting board. Using a sharp knife, carefully create a pocket in each breast by slicing horizontally, making sure not to cut all the way through.
4. Stuff the Chicken: Spoon an equal amount of the stuffing mixture into each chicken pocket. Use toothpicks or kitchen twine to secure the openings.
5. Season the Chicken: Drizzle olive oil over the stuffed chicken breasts and season with salt and pepper on both sides.
6. Bake: Place the stuffed chicken in a baking dish. Bake in the preheated oven for 30-35 minutes or until the chicken is cooked through and no longer pink in the center.
7. Prepare Oregano Oil: While the chicken is baking, combine the remaining olive oil and fresh oregano in a small bowl. Let it sit to infuse the flavors.
8. Rest the Chicken: Once cooked, remove the chicken from the oven and let it rest for 5 minutes before slicing.
9. Drizzle Oregano Oil: Just before serving, drizzle the oregano oil over the stuffed chicken for an extra burst of flavor.
