Drain and rinse the black beans and set aside.

In the crock pot, combine the diced sweet potatoes, chopped onion, minced garlic, chopped bell pepper, black beans, and diced tomatoes.

Add the chili powder, cumin, smoked paprika, salt, and black pepper to the mixture.

Pour in the vegetable broth and stir everything together until well combined.
