Quesadilla comes from the Spanish word "queso," which means cheese. A quesadilla is a tortilla filled with melted cheese and other ingredients like meat, vegetables, or beans. It's then folded in half and grilled until crispy on the outside and gooey on the inside - yum! In addition to their literal meaning, quesadillas have become a staple food item for many people worldwide due to their versatility and deliciousness. You can customize them with various fillings or dip them in salsa, guacamole, or sour cream for added flavor.
