In a soup pot over medium heat, saute the onions with a pinch of sea salt in olive oil for 3-4 minutes until the onions are translucent.
Add the chopped squash and saute until it begins to wilt and release liquid, approximately 5 minutes. Add the broth or water and bring to a boil. Cover, reduce the heat, and simmer until the squash is soft.
Turn off the heat and add the dill. Puree the soup in a blender or directly in the pot with an immersion blender for a smooth texture. For a chunky soup, puree about 1/4 of the soup in a blender until smooth, then add back to the pot. Season with lemon juice, additional sea salt, and black pepper to taste. Garnish with fresh chopped herbs.
