Ground Italian Sausage - Make sure to choose an Italian sausage for this, you can use sweet, hot spicy Italian sausage, or a combination. You want to check your sausage for added sugar. Make sure to choose one without any sugar in the ingredients list.
Diced Tomatoes in Juice - Do not drain the juice, it enhances the flavor of the soup.
Chicken Stock - I use carton chicken broth or make my own with my homemade chicken bouillon.
Kale or Spinach - Kale is the more traditional choice but my family prefers spinach, either work!
Heavy Cream - if you would like this soup to be dairy-free just omit the heavy whipping cream.
Mire Poix - This is a combination of chopped onions, carrots, and celery.
Spices - I use a simple combination of salt and ground black pepper since this gets so much flavor from the other ingredients.
