Preheat the grill to high. Heat the oil in a frying pan and fry the chicken over a high heat until browned all over. Add the dried herbs and passata and season well with salt and pepper, then add the courgette spaghetti and warm through until a little softened.
Transfer to a roasting dish. Mix the cheeses with the breadcrumbs and scatter all over the top of the dish. Pop under the grill for 4–5 minutes until golden and bubbling.
Serve scattered with basil leaves.
Notes
A speedy twist on an Italian classic. You can find pre-prepared courgette spaghetti in many supermarkets or easily make it yourself with a julienne peeler.
