Cottage Pie

Oven 180°C/fan 160°C/gas 4, then a quick blast under the grill to brown the top; rest 5 minutes before serving. Boil and mash the potatoes while the mince simmers (store-bought mash works in a pinch). Mushrooms, frozen peas or corn can be added to the mince. Freezes well, baked or unbaked, for up to 1 month.
