Sally Bee serves up a hearty shepherd’s pie for winter warmer on Lorraine.

Sally says: “Shepherd’s pie is an old tradition in many households and this is a version of my mother’s recipe. As always, ensure you use great quality, very lean minced beef. Red meat contains iron and zinc and this is complemented by the vitamin C and fibre content of the potato and sweet potato topping. The onions, garlic and tomatoes will help lower blood cholesterol making this dish a lovely, filling, nutritious meal.”

The ingredients are: 600g white, floury potatoes, peeled and diced, 600g sweet potatoes, peeled and diced, freshly ground black pepper, to taste, 3 tbsp semi-milk, 400g extra-lean minced lamb or beef or turkey, 1 medium onion, peeled and chopped, 1 celery stick, chopped, 2 garlic cloves, peeled and crushed or chopped, 2 tsp plain flour, 450g canned chopped tomatoes, 300ml cups vegetable stock, 1 slug of Worcestershire sauce, 2 bay leaves, handful of fresh rosemary, leaves picked and chopped and handful of fresh oregano, chopped, or a good sprinkling of dried herbs if fresh not available.
