In a large pot over medium heat, add the ground beef. Cook until browned, breaking it apart with a wooden spoon, about 5-7 minutes. Drain excess fat if necessary.
Add the chopped onion, minced garlic, and diced bell pepper to the pot. Sauté for about 3-4 minutes until the vegetables have softened.
Stir in the taco seasoning, cooking for an additional minute to allow the spices to bloom.
Pour in the beef broth and canned diced tomatoes with their juice. Bring the mixture to a simmer.
Add the uncooked pasta to the pot, stirring to combine everything. Cover the pot and let it simmer for about 10-12 minutes, or until the pasta is al dente, stirring occasionally.
Once the pasta is cooked, stir in the black beans and corn. Cook for another 2-3 minutes until heated through. Adjust seasoning with salt and pepper to taste.
Remove from heat and sprinkle shredded cheddar cheese over the top. Cover the pot for a few minutes until the cheese melts.
Serve hot, garnished with freshly chopped cilantro and lime wedges on the side.
