Mum's Cottage Pie
Recipe can easily be doubled to feed a family of 4.
Use your choice of grated cheese.
Tastes best made the day before if possible. If freezing, make as above and chill in the fridge. Cover with a layer of aluminum foil and a layer of plastic wrap (ensure your casserole dish or tin is freezable). Defrost completely before reheating. I tend to cook when it has been frozen and defrosted with the foil still on (remove plastic wrap) for 20 minutes and the remaining 10 minutes uncovered.
