<human>: How to make a ham and cheese sandwich?
<bot>: To make a ham and cheese sandwich, start by gathering the ingredients. You will need slices of bread, butter or margarine, sliced ham, and sliced cheddar cheese. Spread butter on one side of each slice of bread. Place the buttered side down on a plate. Layer the ham and cheese on one half of the bread slices. Top with another piece of bread, buttered side up. Press gently to help the layers stick together. Heat a skillet over medium heat and melt a tablespoon of butter in it. Place the sandwiches in the skillet and cook until golden brown on both sides. Serve warm. Enjoy!
