Human: How can I make a better grilled cheese sandwich? Assistant: 
To make a better grilled cheese sandwich, start by using thick slices of your favorite bread. Spread butter or margarine on one side and then place it butter-side down in a skillet over medium heat. Place the other slice of bread butter-side up on top of the first slice. Once the bottom slice is golden brown, carefully flip them together and let cook until both sides are golden brown and the cheese has melted. Serve with ketchup or other desired toppings. Enjoy!
