Tortilla chicken casserole
Preheat the oven to 180°C/ 350°F/Gas mark 4. Lightly grease a 23cm/9in square baking dish with vegetable oil.
Combine the chicken, green chillies, cheese, soup and milk.
Place 4 tortillas in the bottom of the prepared baking dish, and spread one-third of the chicken mixture over the tortillas. Repeat the layers until all tortillas are used, ending with chicken mixture. Top with the crisps. Bake for 30 minutes until bubbly. Serve immediately
