This must be cooked with lamb mince (shepherds looked after sheep = shepherds pie + lamb/ mutton mince! cottagers looked after cows = cottage pie + beef mince). This is also a great way to use up the leftover Sunday Roast if you have a mincer, as you don't have to cook the mince before it goes in the oven. I said that it takes 1 hr to prepare, but this is for uncooked mince. 10 minutes for cooked mince, just combine it in the dish and put the potatoes on top and pop it in the oven! This can either be served with salad, or hot veggies.
