Heat a large pot over medium heat. Add the ground beef and cook until browned, breaking it up with a spoon as it cooks.
Add the diced onion, minced garlic, and red bell pepper to the pot. Cook for 5 minutes until the vegetables soften.
Stir in the cumin and chili powder. Cook for 1 minute until the spices smell fragrant.
Pour in the beef broth, then add the drained black beans, diced tomatoes, and frozen corn.
Season with salt and pepper. Bring the stew to a simmer and cook for 20 minutes, stirring occasionally.
Ladle the stew into bowls and top with chopped cilantro. Serve with lime wedges on the side.
