What’s great about cream of mushroom soup is that it can be eaten alone, served as a side, or used in other main courses. If you’re serving it as the main course, a delicious salad like this Celery & Apple Walnut Salad, Moroccan Carrot Salad, or Zucchini Noodle Salad would be perfect. If you’re serving it as a side, it would pair quite nicely with this Vegan Mushroom Wellington for a special meal.
