Pappare means "to gobble up," in Italian, which is the destiny of this dish (particularly in Tara's house, where her husband, Chris, makes it most Sunday nights). I like it spicy, but the quantity of harissa can easily be reduced. Make the sauce 3 days ahead if you like and keep in the fridge until needed.
