Vegetarian Matzah Ball Soup
I am almost sure matzo ball soup is on the menu at Kiva's, a restaurant that doesn't serve meat. I can't vouch for it, I got to assume they use a matzo ball mix (which seem to provide better results than made from from scratch 9/10ths of the time) along with that Osem vegetarian chicken soup powder.
