K.J. Foods Chicken & Spinach Dumpling is a delicious and convenient food for a healthy and active lifestyle. And all ingredients are sourced locally, highest quality fresh meat, wheat flour, vegetable, and much more. It can be served in soup or with soup or sauce on the side. If served dry (steamed or fired), dumplings may use any dipping sauce, just like pierogi. One old recipe of sauce is based on dark vinegar. Some additional ingredients can be added to fit your preference, such as diced ginger and/or garlic. Hot sauce is popular too. Pure sugar, or no sauce at all, is also an option.
