In a large, heavy bottomed pot, heat the olive oil over medium heat until it shimmers.
Add the sweet potato, celery, carrots, and onions to the pot. Season with salt and pepper. Cook stirring frequently for 5-7 minutes, or until the sweet potato is softened.
Add the ginger, tomato paste, jalapenos, cumin, and smoked paprika to the pot, and stir well for 1 minute.
Stir in the chicken broth, tomatoes, and peanut butter. Bring to a simmer, cover, and reduce heat to medium-low. Cook for 15 minutes, or until the sweet potatoes are tender.
Add the greens to the pan, and stir well.
Simmer for 5 minutes, or until completely wilted.
Divide the soup between bowls, and garnish.
