This could be oversimplifying things, because there’s really not that much difficulty to an unfrozen grilled cheese sandwich. Does freezing them really make them easier? Yes, and no. It’s not less work, it’s just sort of work that can be done ahead, when you have more time. (But my teenage son likes Freezer Ready Grilled Cheese it because it’s not work that he has to do!)
We served these with Slow Cooker Creamy Tomato Soup and it was, to be completely honest, a killer combo.
