Human: What is the best way to make a grilled cheese sandwich? Assistant: 
The best way to make a grilled cheese sandwich is to start with two slices of your favorite bread. Spread butter on one side of each slice, then place them butter-side down in a skillet over medium heat. Once the butter has melted, add your desired amount of cheese and let it melt completely. Place the other piece of bread butter-side up on top of the cheese. Let the sandwich cook until golden brown, then flip it onto a plate and enjoy!
