Step 1

Add teaspoon of oil to bottom of a large pot. Heat to medium and add onions, celery and garlic. Cook about 2 minutes to release flavors. Add ground beef and continue to cook until meat is browned. Drain fat.

Step 2

Sprinkle the dried basil over beef mixture and then sprinkle 2 tablespoons of flour over as well; cook and stir 2 minutes. Stir in broth and potatoes. Bring to a boil, stirring occasionally; reduce heat. Simmer, covered, about 10 minutes or until potatoes are tender.

Step 3

Stir in diced tomatoes, cheese, tomato paste, ketchup and mustard. Cook and stir until cheese melts and soup comes to a gentle boil. Stir in milk and heat through.

Step 4

Serve with desired condiments.
