This is a great cold weather recipe. You can use any tomato soup, though I prefer to use a natural brand with lower sodium. You will get enough sodium from the canned ingredients. I used Rotelle tomatoes with jalapeño peppers. The amount of spinach and kale is done to your taste. The turkey is optional. I made two portions, 1 with turkey (using 3/4 of the recipe and I substituting black beans (using 1/4 of the recipe). You can substitute any other bean you like. If making a full recipe vegetarian style, use 3 cans of assorted beans. I like to top off this soup with a gorgonzola cheese.
