In a baking dish layer some aubergine slices, then follow with a layer of tomato/mushroom sauce on top. Sprinkle some cheddar and add some mozzarella slices. Continue with another layer of aubergine, followed by tomato sauce and finish by topping with remaining cheddar and mozzarella. Sprinkle some parsley on top and bake for 25 minutes or until brown and bubbling. Enjoy with a side salad.
