In a large saucepan, combine the broth, celery, carrots and onion. Bring to a boil. Reduce heat; cover and simmer for 5-7 minutes or until vegetables are crisp-tender. Stir in the V8 juice, tomatoes, tomato paste, oregano, pepper and garlic powder. Cover and simmer for 40-45 minutes.
Meanwhile, in a skillet, cook pork over medium heat until no longer pink; drain. Add meat and beans to soup; cover and simmer 30-45 minutes longer or until heated through. Stir in pasta just before serving. Garnish with Parmesan cheese.
