Spices often used in Moroccan cuisine like turmeric, cumin, cinnamon and black pepper give this soup complexity and deep flavor. Make it a day ahead, if you can, to give the spices time to mingle and develop. This easy slow-cooker recipe makes it a cinch to get the soup cooking while you do other things.
