<human>: How can I make a great sandwich?
<bot>: To make a great sandwich, start by selecting your favorite ingredients. Consider what type of bread you would like to use and how much filling you want in each slice. Then, spread the desired amount of butter or mayonnaise onto one side of each slice of bread before adding any other toppings. Next, layer the fillings on the bottom piece of bread. Finally, top with another slice of buttered bread and enjoy!
