Like a grilled cheese, but fancier. Imagine you're going out to dinner, you ask to see the "fancy" menu. So the waiter walks you to the back of the restaurant, down a flight of stairs, past a dark hallway that leads into an extravagant seating area filled with chandeliers on chandeliers. You're handed a menu with just one time - "Fancy Grilled Cheese." This is that grilled cheese you would be served. Enjoy :)
