Sweet potato chunks, hominy and pinto beans are simmered in smoky, spicy broth to make this warming vegan sweet potato posole.
Coat the bottom of a large pot with olive oil and place it over medium heat. When the oil is hot, add the onion and poblano pepper. Sauté for about 5 minutes, until the onion is soft and translucent. Add the garlic and sauté for about 1 minute more, until very fragrant.
Stir in the broth, tomatoes, beans, hominy, cumin, oregano, and chipotle chile powder and sweet potato. Raise the heat and bring the broth to a simmer. Lower heat and allow to simmer, uncovered, until the sweet potato is tender, about 20 minutes.
Remove from heat and season with salt and pepper to taste.
Ladle into bowls and serve with cilantro and lime wedges.
This soup has a mild kick to it. If you prefer a heat-free version, swap the poblano pepper with a bell pepper and substitute a teaspoon or two of smoked paprika for the chipotle chile powder.
