The recipe takes me back - usually using ground beef, canned or frozen veggies, & mashed potatoes. But, I have seen many variations using mashed sweet potatoes, ground turkey or leftover roast beef, thinly-sliced russets over the top drizzled w/ butter, beer/tomato paste/veg or beef broth added to the "gravy", prepared in ramekins or a casserole dish. Get jiggy w/ it. ;-)
