Easy Cheeseburger Soup

1 In a large stock pot, add the onion, carrots and celery and cook on medium/high heat for 7 minutes. If using a fresh onion, add a tablespoon of oil for cooking. If using frozen onion, it will release some liquid so no oil is needed. 
2 Add the beef and salt and cook while breaking into small pieces. A wooden spoon works great for this. Add the broth and potatoes, cover and reduce heat to a simmer. Cook for 20 minutes or until the potatoes are tender stirring regularly. 
3 Remove the lid and add the goat cheese and milk and cook uncovered for 5 minutes. Serve hot. Add additional toppings if desired like bacon, more cheese, and green onion.
