Peel and cut up all the vegetables into your desired shape and size.
Place them in a 6 quart pot.
Put the chicken legs in a mesh bag and tie it up. Put the parsley in a mesh bag and tie that as well. Place both bags in the pot.
Fill the pot up with water, until its covering most or all of the vegetables.
Add salt. Bring the soup to a boil, and skim any scum that comes to the top.
Cover and place the pot on a very low flame. Cook for about 12 hours.
Season with additional salt to taste.
Store in the fridge for 3-5 days or in the freezer for 4-6 months. (The vegetables will get very soft when they are frozen.)
