Dice the onion, bell pepper, and tomato. Mince the garlic.

In a saucepan, heat a little oil over medium heat. Add the onion and bell pepper, and sauté until softened, about 5 minutes.

Add the garlic and cook for another minute until fragrant.

Stir in the black beans, diced tomato, cumin, chili powder, salt, and pepper.

Pour in the vegetable broth and bring to a simmer. Cook for about 20 minutes, stirring occasionally.

Remove from heat, garnish with chopped cilantro, and serve with lime wedges.
