Preheat oven to 180 degrees fan forced and place rack into middle of oven
Rub a little butter onto the base and sides of your baking dish
Place a small amount of the extra 300g passata sauce on the base of the dish, leaving the balance for topping the enchiladas
Place a wrap onto a flat surface (I use my digital scale so that I can check I am sticking to 125g chicken filling)
Fill with 125g filling, roll up and place into baking tray
Continue until you have 8 wraps completed
Top with the rest of the passata sauce
Sprinkle over the cheese
Bake for 20 minutes, turn tray around and bake for a further 10 minutes until nice and golden, rest for 5 minutes before serving
Serve with the sour cream sauce, avocado and salads of choice
