Step 1

Heat the oil in a large pot over medium heat. Add the onion and salt and sauté until the onion is translucent, about 5 minutes. Add the garlic, cumin, coriander, and chili powder and stir for 30 seconds. Stir in the beans, chipotles, adobo sauce, and broth and simmer for 30 minutes.

Step 2

Let cool slightly and transfer half of the soup mixture to a blender. Puree until smooth, then add it back to the pot with the remaining soup and stir. Stir in the lime juice. Serve with lime wedges and desired toppings.
