Instead of cooking your chicken in the broth, try using an herb-roasted chicken. Use whatever herbs you like...I like S&P,parsley, sage or rosemary, and thyme. Rub the chicken well, inside and out, with olive oil and the herbs and roast using your usual method.
Use purchased or homemade chicken broth for the soup, and add the drippings from the roasting pan. Add chopped onion, a little garlic, celery, carrot, cut up chicken and noodles...either homemade or a good substantial packaged egg noodle.
Or, skip the noodles and use rice instead.
Or, skip the rice and add potatoes, mushrooms, green beans, corn and frozen peas.
By the way, I love brussels sprouts, and did try putting them in the chicken soup once, but I didn't like the taste they gave the soup.
*Note: I have tasted chicken soup that had a little curry powder in it, and it was very good. I'm not experienced with using curry, and haven't tried using myself.
