Sure! You really only need a recipe for the dumplings...the soup you just make a chicken soup, in a big pot sauteeing a chopped onion, and roughly that amount of celery and carrots in some butter, with a little salt, pepper, thyme...splash of white wine optional. Add 1-1/2 quarts chicken stock, either home made or store bought, bring to simmer. Meanwhile, you need cooked chicken. Easiest to use leftovers or bake a half chicken or whatever pieces you like, let it cool, and cube the meat. Add the chicken and any drippings to the pot and let simmer 45 min or so.
Dumplings: whisk or sift 1-1/4 cups flour, 1 tsp baking soda, 1/2 tsp salt. Add 3 Tbsp minced parsley and 2 tsp ground pepper. Cut in 3 Tbsp very cold butter, then stir in 1/2 cup or more buttermilk. Turn onto floured surface, knead just enough so you can work with it, roll or pat to 1/2" thickness. Turn up the burner to medium. With sharp knife, cut dough into 1/2" wide strips. Cut your strips into 2" lengths, drop one at a time into the soup. Stir once gently to separate dumplings. Cover tightly, pick up the pot and swirl it around some to move the dumplings around. Let cook 20 min without uncovering. Now it's ready! Squeeze half a lemon and stir in a cup of milk and add more salt/pepper to taste.
Thanks for asking, Doug, now I'm going to make some tomorrow.
