In a large pot or Dutch oven, cook the ground beef over medium-high heat, breaking it into small pieces as it cooks.
Once browned, add the taco seasoning, tomato sauce, diced tomatoes, corn, milk, and broth mixing well to combine.
Bring to a light boil and simmer for 5 minutes.
Add the pasta, stirring well to combine.
Cover and simmer for 8-10 minutes, until the pasta is cooked.
Remove from heat and stir in the cheese.
Serve topped with chopped green onions.
Enjoy!
