Method
Heat olive oil in a large pot over medium heat. Add the onion and cook for 3–4 minutes, stirring occasionally, until softened and translucent.
Stir in the garlic, carrots, and celery. Cook for 5 minutes, stirring occasionally, until the vegetables begin to soften.
Add the sweet potato, cumin, and smoked paprika. Stir to coat the vegetables evenly with the spices and cook for 1 minute until fragrant.
Pour in the vegetable broth and diced tomatoes with their juices. Bring to a boil, then reduce heat to low and simmer for 15 minutes, uncovered.
Add the chickpeas and kale. Simmer for another 5 minutes, or until the kale is wilted and the sweet potatoes are tender.
Season with salt and black pepper. Taste and adjust seasoning if needed. Ladle the soup into bowls and garnish with fresh parsley before serving.
