I was asked to bring a soup for a group of friends getting together for a casual, coastal overnight in beautiful west Marin. There were a number of recipes that were contenders, but a spicy chickpea soup from Yotam Ottolenghi's upcoming cookbook, Plenty More, caught my attention. It features a seductive, red harissa broth fragrant with cumin, coriander, and caraway, and enough chickpeas and bulgur to make it work as a main course. An herb-whipped feta is the crowning dollop.
