This is another one of those recipes that you can change-up how you want by adding different veggies. I tossed a Parmesan cheese rind into mine for added flavor but it can be left out and taste just as good. I used fresh spinach I chopped up into smaller pieces but you could use frozen also if you prefer. Just be sure to drain it well by squeezing it in a kitchen towel to force out the moisture (once thawed of course.) Then just chopped it up and add it in when you do the chicken. You can use fresh basil if you like, but just add it in when you add in the chicken to keep the flavor bright. I served it with a crusty bread, which I highly recommend to soak up the soup. It is pretty darn tasty!
