Turkey sausage, sweet butternut squash, earthy mushrooms, shallots, and spinach come together to make a big bowl of delicious comfort. The colors stay intact, and the sausage is perfect for sopping up with some crusty French bread. Best of all, it’s fast and easy, and you can dress it up or down. Turkey Italian sausage has less fat, but still retains lots of flavor. Brown the shallots and mushrooms first—since the turkey sausage doesn’t have much fat, it will burn on the bottom of the pot. This soup also works well as leftovers, especially with crusty bread.
