In a large soup pot or dutch oven, heat 3 tablespoons of olive oil on medium setting. Add onion, carrot and celery. Season with 1 teaspoon of salt. Cook until vegetables begin to soften, about 4-5 minutes. Add stock and chicken. Simmer for about 10 minutes.
Meanwhile, pulse all meatball ingredients in food processor until they become a thick paste. Roll loosely to form small mini meatballs, about 1 inch in size. Set aside.
Bring soup to a boil. Add meatballs and cook in soup for about 4-5 minutes; until cooked through. Reduce soup back to a simmer. Gently stir in Tortellini and cook for al dente texture. Add in chopped parsley.
