In a large saucepan coated with cooking spray, cook shallots in oil over medium heat until tender. Stir in the broth, squash, potatoes, water, thyme and pepper.
Place cloves on a double thickness of cheesecloth; bring up corners of cloth and tie with string to form a bag. Stir into soup. Bring to a boil. Reduce heat; cover and simmer for 10-15 minutes or until vegetables are tender. Stir in turkey; heat through. Discard spice bag.
