My gran used to fry off onions and sage in a pan and then add an array of her favourite leftovers. I do the same now, just with all the veg. It makes a hearty Northern, crispy fried leftover sandwich. Don’t forget to bring back any leftover cranberry or apple sauce sauces to dress it, and finish with a splash of gravy.
