Place a large pot over medium heat and add the ground beef. Cook until browned, breaking it up with a spoon as it cooks. Drain any excess fat.
Add the chopped onion, minced garlic, and diced red bell pepper to the pot. Cook for 3 to 4 minutes until the vegetables soften.
Stir in the chili powder and ground cumin. Cook for 1 minute to toast the spices.
Add the drained black beans, drained corn, diced tomatoes with green chilies, and beef broth. Stir everything together.
Bring the mixture to a simmer and cook for 10 minutes, stirring occasionally. Season with salt and pepper to taste.
Ladle the stew into bowls and top with chopped cilantro. Serve with lime wedges on the side.
