Leftover mashed potatoes are mixed with white cheddar cheese to form the top crust for this British pub-food staple. Ground beef is traditionally used, but lean ground turkey will work, as well. Brown the crust under the broiler for a minute or two, if you like.
This is what happens when the good ol' chicken casserole takes a trip to the land of enchantment. You get an easy-to-love casserole with cheesy rice and a spicy kick.
