Shepherds Pie or sometimes spelled Shepards Pie, is a dish that is served at pubs throughout England and Ireland. It is traditionally made with finely chopped or ground lamb topped with mashed potatoes. Ground or chopped beef is often substituted for the lamb. When beef is used, the dish is referred to as "Cottage Pie". I am not a big fan of Lamb, so I used ground beef in the recipe that follows. My wife and I absolutely loved this dish and will certainly make it again in the future. The ground beef was excellent, but I think the next time I make this, I will try using a braised beef instead. I am thinking that some left over meat from a pot roast would work wonderfully in this dish.
