Chop carrots and celery. Place tomatoes, celery and carrots in a pot and boil for about 10-15 minutes. Once veggies are soft, puree in a blender until smooth. Optional: Juice your carrots and celery if you have a juicer to make a sauce that is more runny, similar to spaghettios. Boil noodles according to package directions. Combine. Season with salt, pepper and parmesan cheese.
