Turkey Soup with Butternut Squash, White Beans and Spinach

1. Heat the oil in a large pot over medium heat until it shimmers. Add the onion, celery, squash, and salt and pepper to taste. Cook for about 3 minutes, until the vegetables begin to soften. Add the stock and the beans, bring the soup to a simmer, and cook until the squash is tender, 12 to 15 minutes. Add the turkey and spinach leaves and simmer for another minute or two until the turkey is heated through and the spinach has wilted.

Ladle into warm bowls and garnish with grated Parmesan to taste.
