Paleo Chorizo Sweet Potato and Kale Stew

"This nutritious soup takes inspiration from the flavors of Spain. Garnish with store-bought (or homemade) harissa to add heat or garnish with a sprinkling of chopped Italian parsley."

Ingredients

Original recipe makes 8 servings
 1 large onion, diced
 2 tablespoons olive oil
 8 ounces Spanish chorizo, cut into 1/2 inch pieces
 3 stalks celery, diced
 3 carrots, diced
 2 teaspoons ground cumin
 1 tablespoon paprika
 1/2 teaspoon ground turmeric
 2 teaspoons kosher salt
 1 teaspoon freshly ground black pepper
 1 pinch saffron threads
 5 garlic cloves, minced
 2 sweet potatoes, peeled and cut into 1-inch pieces
 8 cups chicken broth
 4 cups lacinato (dinosaur) kale - washed, stemmed, and torn into pieces
 1 lemon, juiced
 salt and pepper to taste
 1 pinch harissa, or to taste (optional)
 1 tablespoon chopped fresh flat-leaf parsley, or to taste (optional)

Directions

1. Cook and stir onion in olive oil in a soup pot over medium-high heat for 5 minutes. Add chorizo and continue cooking, stirring frequently, for another 3 minutes.
2. Add celery and carrots; continue stirring and cooking until vegetables have softened slightly, about 3 minutes. Add cumin, paprika, turmeric, kosher salt, ground black pepper, saffron threads, and garlic. Cook and stir until garlic is fragrant and slightly soft, 3 more minutes.
3. Add sweet potatoes and chicken broth. Bring to a boil, reduce heat to medium-low, and cook until sweet potatoes are tender, about 20 minutes. Add kale and cook until vegetables are soft and the kale is wilted and cooked through, about 10 more minutes.
4. Stir in lemon juice; adjust salt and ground black pepper to taste. Garnish with harissa and parsley.
