For the soup: Heat the olive oil in a Dutch oven over medium-high heat. Add the chorizo, onions, garlic and jalapeno and saute until tender, about 4 minutes. Add the black beans, chipotle pepper, adobo sauce and broth and simmer for 25 minutes so all the flavors can marry together.

Blend half of the soup, using either a blender or an immersion blender, leaving some whole beans for texture.

For the sour cream: Mix all the ingredients in a bowl.

Taste for seasoning and plate topped with cumin lime sour cream and sliced green onions.
