Use chicken sausage as a flavorful alternative to pork sausage. Cut potatoes evenly for uniform cooking. Don’t overcook kale; it should remain tender with some bite. Adjust red pepper flakes to taste. For a lighter or dairy-free version, substitute heavy cream with coconut or plant-based cream. Let soup rest after cooking to meld flavors. Variations include vegetarian versions with smoked tempeh or mushrooms and swapping greens or potatoes.
