Which item is NOT included in the Grilled Cheese and Tomato Bisque?

The Grilled Cheese and Tomato Bisque typically features a blend of cheeses that enhance the creamy and savory flavors of the dish. In this specific combination, Fontina, Swiss, and Cheddar cheeses are commonly included due to their meltability and flavor profiles that complement each other well. These cheeses contribute to the rich texture and taste that guests expect from a classic grilled cheese sandwich.

Parmesan cheese, while flavorful, is not part of this specific recipe as it is typically used as a finishing cheese rather than a melting cheese in a grilled cheese sandwich. Its distinct sharp and nutty taste does not align with the traditional flavors sought in a grilled cheese context, making it the correct answer as the item not included in the Grilled Cheese and Tomato Bisque.
