Lamb and Chick-pea Soup

This dish is not native to Scandinavia but is from North Africa. My reason for preparing it in this way was purely practical. I had to cook a substantial, tasty, one-pot dish on the rolling deck of a 320-foot-long, four-masted schooner for around twenty people who had just come off an arduous watch, raising and trimming sails and frigging in the rigging.
