Steps
1. Preheat your oven to 375°F (190°C).
2. In a small bowl, combine cream cheese, mozzarella cheese, minced garlic, oregano, salt, and pepper.
3. Carefully cut a pocket in the chicken breast and stuff it with the cheese mixture.
4. Heat olive oil in a skillet over medium heat and sear the stuffed chicken for 3-4 minutes on each side until golden brown.
5. Transfer the chicken to a baking dish and bake in the oven for 20-25 minutes, or until the chicken is cooked through (internal temperature of 165°F or 75°C).
6. Let it rest for a few minutes before slicing and serving.
