I'm with Yehudis. I'm generally a flexible person, but broccoli and mushrooms do NOT go in chicken soup.
Matzo Ball Soup
From EatingWell: January/February 1995
Floating in a flavorful broth, our matzo balls are light and fluffy but bound together with whisked eggs and only a small amount of canola oil rather than the traditional chicken fat. Plus, this version of Jewish penicillin has plenty of added vegetables, making it a good source for vitamins A and C. Now that's what Doctor Mom ordered!
