Human: What's the best way to make a grilled cheese sandwich? Assistant: 
The best way to make a grilled cheese sandwich is to butter one side of each slice of bread, then place them buttered-side down in a skillet over medium heat. Add your desired amount of cheese slices and let them melt until they are golden brown. Once both sides have been lightly toasted, carefully flip the sandwich with a spatula and cook for an additional minute or two on each side. Serve hot and enjoy!
