Once you taste it I'm sure you'll agree that it really is the best grilled cheese sandwich!
Heat a cast iron skillet over medium heat. While skillet is heating generously butter one side of one of the slices of bread.
Place the slice of bread buttered side down in the skillet. Top with the cheese.
Butter the other slice of bread and close the sandwich with the buttered side facing up.
Cook until the bottom of the sandwich is nicely browned. This shouldn't take but a minute.
Next flip the sandwich over and brown the other side.
Serve and enjoy!
