In a large soup pot, add turkey carcass, water, onion, celery sticks and carrots. Season with salt and pepper. Cook for about 1 1/2 hours.
Remove carcass and everything else from the soup, using a]mesh strainer or a slotted spoon, keep the carrots. All there should be left in the pot should be the broth. Add turkey meat noodles to the pot. You might need to add a couple more cups of water as some of it may have evaporated. Chop the cooked carrots and add to pot. You can also chop the cooked celery and add to the soup, but I'm not a fan, so I skipped it. Season with salt and pepper and add the bouillon cube or vegeta. Cook for another 8 minutes until noodles are cooked.
Garnish with parsley.
