Tagine is the name for a type of earthenware vessel as well as the stew-like dishes that are cooked in it. They are popular throughout North Africa and differ among locales. This one is my own invention, but the addition of harissa gives it a Tunisian spin. I love the juxtaposition of hot and sweet flavors. It is easy enough to make for a weeknight meal, but with a tiny bit of dressing up, it is also perfect for guests.
