In 5-quart Dutch oven or saucepan, heat 3 teaspoons of the oil over medium heat. Add onions to oil; cook 10 minutes, stirring occasionally, until golden brown. Add all spices; stir until onions are well coated. Cook about 3 minutes, stirring frequently, until glazed and deep golden brown. Stir in squash; coat well with seasoned mixture. Stir in broth, tomatoes and chickpeas. Heat soup to boiling; reduce heat. Cover and simmer about 15 minutes or until squash is tender.
