Season each chicken breast with salt, pepper, onion powder and garlic powder. Set aside.In a bowl, combine sun dried tomatoes, ricotta cheese, spinach and garlic. Season with salt and pepper to taste. Slice each chicken breast in the middle without cutting all the way through to the other side, so it creates a pocket. Fill each breast with half of the filling. Add a slice of mozzarella cheese on top of the filling inside of each breast.Heat a large oven safe skillet over medium heat. When hot, add the olive oil. Sear each chicken breast on each side, carefully turning them over so the filling does not come out. Pour Alfredo sauce over the chicken. Add basil on top to garnish. Place pan into a 350 degree oven and bake for 15 minutes or until the chicken is done throughout.Remove from the oven, sprinkle on Parmesan cheese and chopped parsley and serve.
