Steps
1. Preheat your oven to 375°F (190°C).
2. In a bowl, mix together the chopped spinach, cream cheese, mozzarella, minced garlic, salt, pepper, and paprika until well combined.
3. Carefully cut a pocket in the chicken breast and stuff it with the cheese and spinach mixture.
4. Heat olive oil in an oven-safe skillet over medium heat. Season the outside of the chicken with salt and pepper.
5. 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, or until the chicken is cooked through.
7. Let it rest for a few minutes before slicing and serving.
