Cheater Chicken Noodle Soup

This is my cheater version of chicken noodles soup, and I'm not sorry about cheating b/c it's good.  I simply bought a rotisserie chicken from the store, removed the skin and shredded the meat.
I started off by taking about a half of cup of chopped celery, chopped carrots, and a medium onion and sautéing them in about a T. of oil.  When they start to soften I added 16 oz of chicken stock and about two cups of water, the chicken, 1 t. of kosher salt, and 1 T of parsley.  I also added about two cups of pasta and boiled it all together for about 15 minutes (until the noodles were soft).  If the water boils out, add more water.  I don't like a lot of water with my soup, but feel to add more broth if you like a soupy soup.
