Quesadilla – a dish of Mexican cuisine – is two tortillas with a filling, which necessarily includes cheese, fried in a frying pan or deep-fried. Due to browning, the cheese in the filling melts and thus holds together both tortillas. Also, instead of two tortillas, you can fold one in half. It is prepared do really quickly and a big advantage is that beside cheese and tortillas, you can use absolutely any stuffing.
