Season the ground beef with salt, pepper and garlic powder, brown in large saucepan. Drain oil and set aside.
In the same saucepan, add 4 tbsp butter, flour and onion, shredded carrots, and celery. Saute until tender, about 3 to 5 minutes.
Next, add the broth, pasta and beef into the pan and bring to a boil. Reduce heat, cover and simmer 15-20 minutes or until the pasta is tender.
Stir in the cheese, milk, and parsley. Taste broth and season with salt and pepper. Stir until cheese melts. Remove from heat, ladle into bowls, top with dill pickle garnish and serve.
