Start by dicing your onions and bell peppers and mincing the garlic cloves. Open and drain the black beans and corn if using canned. Measure out your shredded cheeses and taco seasoning so everything is ready to go.
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with your spoon, until browned and no longer pink. Season lightly with salt and pepper.
Add the diced onions, bell peppers, and minced garlic to the beef. Cook for about 4-5 minutes until softened and fragrant. Sprinkle the taco seasoning over the beef and veggies, stirring well to coat everything evenly.
Pour in the cup of chicken broth and diced tomatoes. Stir to combine, then add your chosen pasta. Bring the mixture to a gentle boil, then reduce heat to a simmer. Cover and cook for about 12-15 minutes, stirring occasionally, until the pasta is tender and has absorbed much of the liquid.
Once the pasta is cooked, stir in the black beans and corn. Then add the shredded cheddar and Monterey Jack cheeses, folding gently until melted and creamy. Adjust seasoning with additional salt and pepper if needed.
Sprinkle chopped cilantro over the top for a fresh, herbal note if desired. Serve hot straight from the skillet and enjoy the perfect blend of cheesy, spicy, and savory flavors.
