Cook ravioli according to package directions. Cook until al dente, 1 minute less than directed. Careful not to overcook ravioli as it will cook in hot soup too. Drain and set aside. Place olive oil in large pot over medium heat. When hot, add onion, carrot, celery and garlic to pot. Cook and stir until softened, about 8-10 minutes. Stir in chicken broth, chicken, cooked ravioli, dressing seasoning, salt, pepper and Parmesan cheese. Stir and reduce heat to simmer. Stir in parsley and simmer until ready to serve. Serve warm with rolls for dipping. Garnish each bowl of soup with additional shredded Parmesan Cheese.
