If you want comfort food on a plate you will find it in this pie that instantly evokes all the cosiness of crisp Autumn evenings. It’s a simple creamy chicken & mushroom filling that can be levelled up with the fanciest looking mushrooms you can find and even a splash of marsala for some depth. As it’s a wonderful one to serve to kids, I add spinach and peas and whatever other veggies I have in the fridge chopped finely alongside to up the nutritional value.Heat half of the oil in a 25-30cm ovenproof frying pan over a medium high heat. Season the chicken and brown all over. Set aside.
