A gourmet grilled cheese sandwich featuring sourdough bread filled with a creamy ricotta, mozzarella, and Parmesan cheese mixture, chopped sun-dried tomatoes, and fresh spinach leaves for a flavorful twist.
Use oil-packed sun-dried tomatoes for extra flavor; drain well before chopping. For a crispier sandwich, press down gently with a spatula while cooking. Wilt the spinach slightly if you prefer less volume in the sandwich.
