I agree pretty much with Therese. Sometimes you can roast some chicken parts along with some vegetables and throw it into the water to make a richer stock. Definitely, make a good stock. Lots of chicken, onion, carrots, celery, thyme, maybe a few slices of ginger, bay leaves, and all the rest of what you would put. I would also not shy away from adding maybe just a little bit of the Jewish soup powder mixes, either Telma or Osem. They are the absolute best soup powders out there...and anyone who's used them would probably agree. Obviously you already want a great, homemade stock, but adding a little bit of those powders will really enhance the flavor of your soup. Don't forget to add frozen peas and chopped parsley at the end for extra flavor and sweetness.
