<<Disclaimer: Verify this information before applying it to your situation.>> There _are_ a number of brands of Kosher for Passover Gefilte Fish that do not contain Matzo Meal (they use potato flour as binder). One of the brands I found last year was "BenZ's Gourmet" Hungarian Style with Jellied Broth. Darker and more flavorful than most other store bought. I don't think you could tell it was GF, if you didn't know. It's distributed by: BenZ's Gourmet Food Products, Inc., Brooklyn, N.Y. 11213. Hope this helps !!! Bob Levy Baltimore, MD
