  it's no longer a grilled cheese, it's a grilled bread and cheese.
  
  If we're gonna be technically correct about this, it's a fried-bread-and-grilled-cheese.
  'Grilled cheese [sandwich]'' is not parsed as 'Cheese sandwich which is grilled' but rather 'sandwich primarily containing cheese which is grilled'. The bread is fried and the dry heat it transfers grills the cheese.
context: I guess butter isn't allowed >
  
  Imo, butter or mayo on the bread in order to toast it is more of the cooking method vs an additional ingredient in the sandwich. >
  
  MAYO?!
  Not judging, but genuinely curious because I’ve never heard of this! 😃 Before or after it’s cooked? What does it do? >
  
  Mayo is sometimes used instead of butter for outside the bread to fry. I haven't yet tried it, but I've seen it done. It gives the bread a good crisp. >
  
  Right.  Just cheese.  Straight cheese.  If you put it between two slices of bread it's no longer a grilled cheese, it's a grilled bread and cheese.
  Calling things by the primary ingredient is not exactly all that weird.
