<<Disclaimer: Verify this information before applying it to your situation.>> Thank you to all that responded! I am excited to try some of the ones I had not known were gluten free. Here are the responses I got that are gluten free: Bearitos Wick Fowler's Old El Paso (If there is gluten in their product it will be on the label) McCormick's Fajita Chi-Chia (TM)s Brand Lawry's Chicken Taco Seasoning Blends and the following from William Foods, Inc.:Williams Cajun Taco, Williams Taco, Williams Tex-Mex Taco. Ortega SAUCE (NOT the seasoning) **I have gotten numberous replies listing ORTEGA medium and hot taco seasoning as gluten free, BUT it is not!! This is what I used to use but when their October 2000 gluten free list came out I saw that there taco seasoning was not on there, so we called and sure enough they said that it now contained gluten. Since I got so many replies for Ortega, I thought perhaps it would be a good idea to call one more time. (I called today, and was told that it is NOT gluten free) If you would like to call yourselves here is the number: 1-800-225-2270 ~Mariah
