Human: Can you tell me how to make a grilled cheese sandwich? Assistant: 
To make a grilled cheese sandwich, start by buttering one side of each slice of bread. Place the slices buttered-side down in a skillet over medium heat. Spread a thin layer of your favorite cheese between two slices of bread and place them on top of the buttered slices. Once the bottom slices are golden brown, turn them over and melt the cheese. Then add any desired toppings like sliced tomatoes, onions or peppers. Finally, place the other slices of bread on top and press down lightly with a spatula. Flip it over again if needed for even cooking. Cook until both sides are golden brown and the cheese is melted. Serve immediately. Enjoy!
