Delicious beef sausages cooked in a tomato sauce. Adapted from "Tunisia: Mediterranean Cuisine" published by Konemann. This recipe has five separate parts. Please read all the directions before you start cooking. Try to time everything so that they're done at the same time. We got pretty close. Also, traditional cuisine would use preserved lemons, but we tried to make our own preserved lemons and they fermented on us. So fresh works too.
