01 - Preheat your oven to 390°F.
02 - Using a sharp knife, make deep cuts about 1/3 inch apart across each chicken breast, being careful not to cut all the way through.
03 - In a bowl, combine the mozzarella cheese, spinach, sun-dried tomatoes, and minced garlic.
04 - Gently stuff the filling into each cut of the chicken breasts.
05 - Place the 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 the chicken is cooked through and the filling is golden and bubbly.
07 - Let rest 5 minutes before serving.
