Mix together flour, eggs and salt and add water as needed to make dough for a ball.
Turn dough on a well-floured board and knead until smooth and elastic.
Cover, let rest 10 minutes.
Divide in half.
Roll out flat and thin and using pastry cutter, cut dough into 2 to 3” squares.
Let dry for at least 1 hour. (You can allow the noodle dough to dry for several hours if desired).
Heat broth (reserved from crockpot, or three 32-oz. containers chicken broth in a large stock pot).
Bring broth to a boil.
Add carrots, celery and onions to the boiling broth; add chicken.
Place noodles one at a time into rapidly boiling chicken broth.
Can remove chicken to allow room and add back later.
Use a fork to make room to drop each square in after all noodles have been added.
Lower temperature and cover stock pot with lid until dumplings are done about 20 minutes.
If necessary, add enough flour to thicken broth a little and add chicken back and simmer or serve.
To serve: ladle chicken and dumplings into bowls and garnish with fresh, snipped parsley and cracked black pepper.
