Lamb Moussaka (Greek Lamb, Potato, and Eggplant Casserole)
Note: The moussaka can be made up to a day in advance. Proceed with recipe just until the beginning of step 6 before you add the cheese sauce. Cover the partially-constructed casserole with plastic wrap and transfer cheese sauce to a sealed container. Refrigerate both for up to three days until ready to serve. When ready, reheat cheese sauce in microwave or on stove, pour over lamb mixture, and bake according to directions.
