Heat olive oil over medium high heat in a large pot for 1 minute or until it begins to sizzle.
Sauté carrots, celery, and onion in olive oil until the onions become translucent and the celery and carrots have begun to soften, about 3 minutes.
While sautéing, season the vegetables with garlic salt and ground black pepper.
Add in the leftover turkey, turkey broth, water, and ditalini pasta. Stir everything together.
Bring to a boil, then cover the pot and reduce to a simmer. Let the soup simmer for 8 to 10 minutes or until the ditalini pasta are al dente and the carrots are fork tender.
Use a ladle to pour your soup into bowls and serve warm with chopped parsley as a garnish, if desired.
Notes
This soup is best enjoyed warm and is a perfect way to use up leftover holiday turkey. Feel free to add other vegetables you have on hand, such as peas or corn.
