This casserole comes out of the oven with a golden crust and a good-food smell that will pull your family to the table. Generous servings and half the calories of a traditional Shepherd's Pie. I make it when I have leftovers in the fridge--cooked turkey/chicken and mashed potatoes. If you don't have cooked chicken in the fridge, buy a rotisserie chicken and low-sodium broth or poach some boneless chicken breasts in water with a bay leaf and thyme.
