Leftover mashed potatoes are mixed with white cheddar cheese to form the top crust for this British pub staple. Traditionally, ground beef is used, but low-fat ground turkey is also suitable. If desired, brown the cake under the roasting rack for a minute or two.

Add the onion and carrot; simmer for 5 minutes. Add the mushrooms; saute for 5 minutes or until lightly browned. Remove the vegetables from the pan. Add the beef to the pan; cook for 5 minutes or until it is lightly browned, stirring until it crumbles. Add the tomato paste and cook for 3 minutes. Add the broth and pepper. Return the vegetables to the pan and bring to a boil. Add the parsley, thyme and salt. Add the flour mixture and cook for 1 minute or until thickened, stirring constantly.Spoon the meat mixture into an 8-inch square glass or ceramic baking dish, smeared with cooking spray to spread evenly. Combine the potatoes and half the cheese; spread the potato mixture evenly over the meat mixture. Top with the remaining cheese. If desired, sprinkle with paprika.
