01 -  Combine spinach, artichoke hearts, cream cheese, shredded mozzarella, grated Parmesan, minced garlic, salt, and pepper in a mixing bowl. Mix thoroughly until even and creamy. 
 02 -  Slice each chicken breast horizontally without cutting all the way through. Open the breasts flat to create a pocket for stuffing. 
 03 -  Evenly spoon the spinach-artichoke filling into each chicken breast, pressing gently to seal. 
 04 -  Brush the outer surfaces of the chicken breasts with olive oil, then sprinkle with paprika, salt, and pepper. 
 05 -  Preheat oven to 200°C (400°F). Place stuffed chicken breasts in a baking dish and bake for 25 to 30 minutes, or until internal temperature reaches 75°C (165°F). 
 06 -  Allow chicken to rest for 5 minutes after baking. Slice and serve while hot.
