To a large dutch oven or soup pot, heat the olive oil over medium heat. Add the onion, carrots and celery and cook for 8-10 minutes or until tender, stirring occasionally. Add the garlic and cook for an additional 2 minutes, or until fragrant. Season conservatively with a pinch of salt and black pepper.
To the pot, add the tomatoes, turnip and red lentils. Stir to combine. Stir in the vegetable stock and increase the heat on the stove to high. Bring the soup to a boil and then reduce to a simmer. Simmer for 20 minutes or until the turnips are tender and the lentils are cooked through. Add the chicken breast and parsley. Cook for an additional 5 minutes. Adjust seasoning to taste.
Serve the soup immediately garnished with fresh parsley and any additional toppings. Enjoy!
