This is a Mexican dish meaning "little cheesy thing". My version is 2 flour tortillas filled with left over roast chicken, which I've shredded, tomatoes, spring onions and lots of cheese. I used tasty cheese but you can use any type of cheese you like. I then placed in a hot dry fry pan to let the tortillas crispen and the cheese melt. This only takes about 10-15 minutes to prepare and cook, making it an excellent quick meal to make during the week.
