In a large pot combine chicken and vegetables. Cover with water. Bring to a boil and reduce heat. Partially uncover and simmer for 2-3 hours. (Add a little bit of water throughout simmering if necessary.)
Strain chicken broth into another pot and discard remains of everything except chicken and carrots. Dice carrots and return to soup. Remove chicken skin and bones and discard. Shred chicken and return to soup. (If using a whole chicken shred half and return to soup. Use the other half for another dish.) Add seasonings (except parsley).
In a small bowl combine egg, salt and baking powder. When ingredients integrate start adding grits while continuously stirring. Noodle consistency should be similar to pancake batter (but not as smooth due to grits granules).
Using a teaspoon grab a little of noodle batter at a time and drop it into soup thus forming noodles (lightly flick each noodle into soup while not touching soup with the spoon). Dip teaspoon into soup after every fourth or fifth noodle to keep prevent grits from sticking. Let simmer 10-15 minutes until noodles expand.
Garnish with parsley and serve.

Notes
Chicken thighs or chicken legs with skin work great. If you can't find some of the vegetables, use what you have.While making noodles drop them into broth. If you try to get the noodle mix off by dipping spoon into the broth with the noodle batter on it noodles will fall apart.As noodles expand five or six times and absorb lot of broth make sure to form smaller noodles. Half a teaspoon of batter per noodle creates perfect sized noodles.If your noodles fall apart add a little more grits. If they're hard, leave them in hot soup longer before serving the soup. If they're too hard use less grits the next time.Why add chicken bouillon to stock you ask? Homemade chicken stock/broth, while fantastic, is not salty enough. Bouillon adds that extra flavor. You can use salt or Vegeta instead, or none at all.
