Make sure all the meat has been removed from carcass. Set aside. In a large kettle or stockpot, throw in whole onion, whole carrot, whole celery, garlic cloves and carcass. Pour water over the top until covered and mixture has 2 inch "head room". Simmer for 3 hours. Strain mixture and discard veggies. If you can get anymore meat off the carcass, do so and add to broth. Now you can throw the carcass out. In the same pot, heat a little olive oil and saute your chopped onions, garlic, celery and carrots for just about a minute on high heat, stirring constantly. Add the broth and simmer veggies until tender, about 20 minutes. Add tomatoes, thyme, noodles and cook until noodles are done. Correct seasoning and serve ladled up in big soup bowls. Yum, yum!!
