A hearty soup/stew from the desert region of Tunisia. Adapted from "Tunisia: Mediterranean Cuisine" published by Konemann. Note: there are a number of good recipes for harissa on Food.com, or you can just purchase it if your local store carries it. Also note: I listed this as "Libyan" in the recipe sifter because there's not an option for "Tunisian" or a generic "North African". I figured since Libya and Tunisia are neighbors, it was the best choice.
