In a large dutch oven, start by sautéing the chopped celery, carrots, and onions in olive oil over medium high heat. You don't need them to be cooked completely but cooked enough so the onions are translucent and the vegetables are fragrant. This takes about 3-5 minutes.
Add the ground turkey to the vegetables and cook until the turkey is almost cooked through and there is only a tiny amount of pink left. This takes 5-6 minutes.
Stir in the Worcestershire sauce, hamburger seasoning, onion powder, garlic powder, salt, and pepper to the ground turkey and veggie mix. Continue cooking until the ground turkey is no longer pink.
Stir in the chicken stock and potatoes, and then bring to a boil.Reduce to a simmer and let it cook for about 10-12 minutes over medium heat or until the potatoes are tender.
Turn the heat to low and slowly stir in the sour cream, shredded cheddar, and parmesan cheese.
Stir until everything it is melted, blended, and smooth. Cook for another 3-5 minutes or until the soup is hot.
Ladle the soup into a bowl and add your favorite cheeseburger toppings to this soup.
