In a large bowl, toss together the shredded chicken, cabbage, cilantro, bean sprouts, onion, bell pepper and chilli. In a small bowl, whisk together the yogurt, chilli sauce and lime juice and pour over salad. Add the yogurt mixture to the chicken mixture and toss to coat.
Place 1 tortilla on a warm griddle or pan, sprinkle it with shredded cheese, then with some of the salad mixture and fold it in half. Heat the quesadilla, turning several times,
until the cheese has melted.
