In a large pot, heat the olive oil over medium heat. Add the onion, bell pepper, and jalapeno. Cook until the onion is translucent and slightly golden, stirring occasionally (about 10 minutes).
Add the garlic, chili powder, ground cumin, cayenne pepper, salt, and black pepper. Cook and stir until fragrant (about 2 minutes).
Add the vegetable broth, tomatoes, and black beans. Stir and bring to a boil. Reduce the heat and simmer for 30 minutes, stirring occasionally.
Add the cooked rice. Stir and cook at a simmer until the stew gets thicker (about 15 minutes).
Season with additional salt & pepper if desired.
Serve with tortilla strips, sliced avocado, chopped cilantro, fresh lime wedge, etc.
Enjoy!
