Heat the 2 tablespoons olive oil in a large skillet over medium heat. Add the 1 chopped onion, 6 cloves minced garlic, 3 sliced carrots, and 1 diced bell pepper. Season with 1 tablespoon salt and 1/2 teaspoon pepper (this will seem like a lot of salt but it will go on to season the entire pot of soup). Sauté for 5 minutes until softened and fragrant. (This step adds extra flavor but can be skipped for convenience.)
Add the 1 tablespoon ground cumin, 2 1/2 teaspoons smoked paprika, 2 teaspoons ground coriander, 1 teaspoon ground cinnamon, the 1 teaspoons ground ginger, and 1/4 teaspoon ground cayenne. Let toast in the oil, stirring for 1-2 minutes or until really fragrant.
Transfer the sautéed vegetables to the slow cooker. Add 1 large diced sweet potato, 1 large diced golden beet, 1 can fire-roasted tomatoes, 2 cups dried chickpeas, 8 cups vegetable broth, and 1/2 cup chopped dried apricots.
Cover and cook on low for 6–8 hours or high for 3–4 hours, until the chickpeas are tender and the flavors have melded together.
Stir in the 1/2 cup chopped cilantro and squeeze the juice of the lemon into the stew. Taste and adjust seasoning with more salt, pepper, or spices as needed.
Ladle the soup into bowls, garnish with additional cilantro, and serve.
