This is a winner using ground lamb or, if you’ve run out, ground beef! It’s a warm ya from the insides dish it is perfect on a chilly day! The picture here is of the meat mixture - I totally spaced off taking a picture of the finished dish! Will try to remember to update this when we make it again.
