From what I understand, once something is added to a grilled cheese sandwich other than sauce or seasoning, it ceases to be a grilled cheese sandwich and instead becomes a melt. But what if you put another slice of bread in between two layers of cheese?
Essentially, bread, cheese, bread, cheese, bread. Does adding the middle layer of bread cause it to become a "bread melt?"
There's no exact answer to this, I would classify this as a triple decker grilled cheese sandwich rather than a melt as you are adding more bread rather than a filling. I would toast the middle piece of bread first to make sure you get a decent crunchy texture.
A burger with a third slice of bread is still a burger. Why would it be different for grilled cheese?
