01 - Preheat oven to 390°F.
02 - Using a sharp knife, make deep cuts about ½ inch apart across each chicken breast, being careful not to cut all the way through the meat.
03 - In a bowl, combine mozzarella cheese, spinach, sun-dried tomatoes, and minced garlic. Mix thoroughly.
04 - Gently stuff the filling into each cut of the chicken breasts, pressing lightly to secure.
05 - Place stuffed breasts in a baking dish. Drizzle with olive oil and sprinkle with Italian herbs, paprika, salt, and pepper.
06 - Bake for 25–30 minutes until chicken is cooked through and filling is golden and bubbly.
07 - Let rest for 5 minutes before serving to allow juices to redistribute.
