If we’re going to get technical, this dish is called shepherd’s pie if you use ground lamb, and cottage pie when you use ground beef. But whatever you like to call it, the classic meat and potatoes dinner is pure comfort food. Here, a savory gravy gives the meat and veggies rich flavor. Going with store-bought refrigerated or deli-counter mashed potatoes, and frozen vegetables, means you can pull it off any night of the week. The recipe is a Yummly original created by Ashley Strickland Freeman.
