<human>:  How do I make a perfect grilled cheese sandwich?
<bot>: To make the perfect grilled cheese sandwich, start by toasting your favorite type of bread until lightly golden. Next, spread butter on one side of each slice of bread. Then, place a slice of cheese on the butter side of each slice of bread. Heat a skillet over medium heat and add the sandwich. Once the cheese on the bottom slice starts to melt, carefully flip the sandwich. Grill the sandwich for an additional 2 minutes, or until both sides are golden and the cheese has completely melted. Serve warm and enjoy!
