Brown the meat and onion in a large pot over medium heat until no pink remains. Drain excess fat if needed.

Add garlic and taco seasoning; cook 30 seconds until fragrant.

Stir in pasta, tomatoes, broth, and corn. Bring to a simmer.

Cover and cook 10–12 minutes, stirring once, until pasta is tender.

Remove from heat and stir in cheese until melted. Taste and adjust salt and pepper.

Serve with cilantro, jalapeños, or sour cream if you like.
