<human>:  How do I make perfect grilled cheese sandwiches?
<bot>: To make the perfect grilled cheese sandwich, you will need two slices of bread, some butter, and your choice of cheese. Spread a layer of butter on the outside of both slices of bread. Place the slices butter-side-down in a frying pan over medium heat. Place a generous amount of cheese between the slices of bread. Flip the sandwich when the bottom slice of bread is golden brown and crispy. Toast the other side of the sandwich until the cheese has melted and both slices of bread are golden brown and crispy. Serve hot and enjoy!
