Set your Dutch oven to medium-high heat, add 2 tbsp of oil, followed by the onion, carrot, celery, garlic, a sprinkle of salt, and your dried herbs. Allow this to sauté for 5 minutes.
While the veggies are cooking, make the dumplings by adding the dry ingredients to a large mixing bowl. Mix the dry ingredients, then introduce the milk. Continue mixing until you have a thick but slightly sticky dough. Let this rest for a few minutes.
Once the veggies are soft and slightly transclucent, add the broth and bouillon cubes. Stir to dissolve the bouillon cubes, then add the turkey.
Once the broth has been brought to a boil, use your hands or a spoon to form balls about 1- 1 1/2 inches in diameter. Introduce these to the boiling broth, trying to keep them at the surface.
Put the lid on and continue boiling the soup until your dumplings are fully cooked - about 10 minutes. Then, serve and enjoy.
