Heat a large soup pot over medium heat. Add a tablespoon of oil and swirl to coat the bottom.
Add the ground turkey to the pot, using a wooden spoon to break it up into small crumbles. Cook the turkey until cooked through and browned, about 5 minutes.
1 lb Italian style ground turkey
Remove the turkey from the pot and set aside on a plate.
Heat the remaining tablespoon of oil in the pot over medium heat. Add onion, carrots, and celery. Sprinkle generously with salt. Sauté, stirring often, for 3 - 5 minutes.
2 TBS olive oil, 1 cup diced onion, 1 cup carrots, peeled and cut into ¼" thick pieces, 1 cup celery, cut into ¼" thick pieces
Add the potatoes, vegetable broth, and cooked turkey. Sprinkle in another generous dash of salt and stir to combine everything.
6 cups vegetable broth, 2 cups potatoes, peeled and cut into ½" cubes
Bring the soup to a boil, then lower the heat to a low simmer. Partially cover the pot with a lid. Let it simmer for 10 minutes or until the potatoes are just cooked through.
Stir in the prepared kale. Let the soup continue to simmer for 2 - 3 minutes.
2 handfuls kale, cut into bite sized pieces
Add in the vinegar and stir to distribute it.
Taste the soup and add more salt if necessary. Enjoy!
