In a large pot, heat olive oil over medium heat. Add the chopped onion and green bell pepper. Sauté until softened, about 5 minutes.
Add minced garlic and cook for an additional minute until fragrant.
Stir in the diced sweet potatoes, chili powder, cumin, smoked paprika, and a pinch of salt and pepper. Cook for 2-3 minutes to allow the spices to coat the veggies.
Pour in the diced tomatoes and vegetable broth, stirring to combine. Bring to a boil, then reduce heat to a simmer.
Cover the pot and let the chili simmer for about 20 minutes, or until the sweet potatoes are tender.
Add the black beans and cook for an additional 5 minutes. Adjust seasoning with more salt and pepper if needed.
Serve hot, garnished with fresh cilantro and a lime wedge on the side for squeezing over the chili.
Notes
Adjust the spice level by adding more chili powder if desired.
