<<Disclaimer: Verify this information before applying it to your situation.>> I'm probably late getting to the party, but is TVP gf? It's textured vegetable protein made by Archer Daniels Midland Co. A newspaper article describes it as being made from soy flour cooked under pressure, squeezed into chunks or flakes, fortified with vitamin B12 and then dried. It is to be reconstituted with boiling water. Thanks for any info anyone might be able to provide. Christina Oldenburg
