Dear Reader, the Yuletide season is upon us and soon we will be awash in Christmas leftovers; roast potatoes, gravy, pigs in blankets, stuffing, cranberry sauce, sprouts and turkey. To help you prepare for this onslaught I’ve devised a turkey and vegetable lasagne that delivers all the comfort-food feelings you need when it’s dark and cold and is also a handy way to use up your Christmas leftover roast turkey (or you can use turkey mince). This recipe is also a bit lower in calories than your regular lasagne, so no need for any feelings of guilt!
