Not all pies are created equal. Some are very special.  March 14 is National Pi(e) Day. 3.14 ha ha, get it? (I know, corny.) Shepherd's Pie, made with primarily lamb, and Cottage Pie, made of beef,  I compromised with the "meatloaf mix" made up of pork, veal and beef. Topped with broiled mashed potato and cheese crust,  this is the best savory option you'll ever come across!
