Steps
1. Preheat your oven to 375°F (190°C).
2. In a bowl, mix the cream cheese, mozzarella cheese, chopped spinach, garlic, salt, and pepper until well combined.
3. Carefully cut a pocket in the chicken breast and stuff it with the cheese and spinach mixture.
4. Season the outside of the chicken breast with salt, pepper, and paprika.
5. Heat olive oil in an oven-safe skillet over medium heat. Sear the chicken breast for about 3-4 minutes on each side until golden brown.
6. Transfer the skillet to the preheated oven and bake for 20-25 minutes until the chicken is cooked through and the juices run clear.
7. Let it rest for a few minutes before slicing and serving.
