<human>:  How to make a cheese quesadilla?
<bot>: To make a cheese quesadilla, start by preheating your oven or a skillet to medium-high heat. Lightly grease a baking sheet or the skillet with oil or butter. Place a large tortilla onto the skillet or baking sheet. Sprinkle cheese onto the tortilla followed by any additional desired fillings. Top with another tortilla. Cook the quesadilla for 3-4 minutes, or until the cheese is melted and the tortillas are lightly golden and crispy. Flip the quesadilla over and cook for an additional 2-3 minutes. Cut the quesadilla into wedges and serve with salsa, guacamole, or sour cream. Enjoy!
