Shepherd's pie is a much-loved classic. We make it using pureed cauliflower instead of potatoes, but typically it's a layered dish made with seasoned ground lamb, a layer of vegetables such as green beans, and then topped with mashed potatoes, which become a beautiful delicious crust when baked in the oven.
