What is the difference between a fajita and a quesadilla?
assistant
The main difference between a fajita and a quesadilla is that a fajita typically consists of thinly sliced meat, such as beef or chicken, cooked on a skillet over high heat with onions, bell peppers, garlic, and other vegetables. A quesadilla is made by layering cheese, ground beef, and/or vegetables between two tortillas, then baking it in an oven until the cheese melts.
