Heat the olive oil in a large soup pot, then add the onion, carrot, celery, scallions and garlic salt. Cook and stir 5 to 6 minutes, or until vegetables begin to soften.
Add the broth, water and butternut squash. Bring to a boil, then reduce the heat to low and simmer for 15 minutes. Add the kale and herbs and simmer an additional 10 minutes. Stir in the beans and heat through. Remove the fresh herb sprigs and discard. Season to taste with salt and pepper, and serve. Sprinkle individual servings with Parmesan cheese, if desired.
