Wash and clean the chicken. Peel the carrots, parsnip, and celeriac. Then chop them into 4-5 long pieces.
Clean the yellow onion and green pepper and fresh parsley. Don't chop them, because we will take them out from the soup and it will be easier to do that if they are in one piece.
Add the chicken pieces, all the vegetables, and fresh parsley into a Stock Pot. Add water until it covers all ingredients. (or a little bit more, if you like more liquids)
Add chicken bouillon cubes, Chicken Flavor Bouillon, and black pepper. Make sure to use the whole black pepper and NOT ground pepper. It's important... because ground pepper can change the color of the soup and we don't want that. Our goal is the golden color.
Leave the soup on HIGH for around 20 minutes then leave it on LOW for another 20 minutes or until all the ingredients are soft and tender.
Meanwhile, boil the noodles, make sure it's not overcooked. Also, when it's ready drain it from hot water. IMPORTANT: add cold water to it, then drain it again, so it can stop getting sticky and gooey.
When all the ingredients are tender, take out the chicken pieces into a bowl, then separate all the ingredients from the liquid with a strainer - colander. So you will have the liquid separate, and all the vegetables separate (with the chicken) in one bowl.
Add all the noodles into the liquid.
For serving, add liquid with the noodles, then if you wish you can add into your plate any ingredient - chicken piece, vegetables.
