Use fresh vegetables. You can chop up carrots, celery and shallots and even add other fresh vegetables if you wish, such as squash, peas, green beans or corn. You can also substitute the spinach for kale if you want but it needs more time to cook so I recommend adding it to the soup with the water, cream of celery and chicken so that it can cook through. You can make this a vegetarian soup by omitting the chicken or substituting tofu instead. If you would like to substitute another type of meat you can do so. Or you can add a bit of texture by garnishing the soup with some crumbled bacon. If you don’t have Gnocchi you can substitute another type of noodle such as egg noodles, shells or macaroni. Be sure to cook as directed on the box or until al dente. Most noodles will need more time to cook through than the Gnocchi does.
