Shepherd's pie is a classic savory pie traditionally prepared from leftovers. Meat and vegetables are moistened with gravy, transferred to a pie plate, and topped with mashed potatoes. The pie is so named because it was often prepared with lamb or mutton.
Assemble the meat cups; cover and refrigerate for up to a day. Uncover the meat cups and bake, adding 3 to 5 minutes to the baking time.
Accompany this recipe with fresh steamed green beans, and bread and butter. Serve sliced melon for dessert.
