<<Disclaimer: Verify this information before applying it to your situation.>> I am hoping to find a GF stir fry mix packet. The kind that you add your own GF soy sauce to. I had a packet in my pantry from before the celiac in our family was diagnosed, but there's modified food starch in it and NO number or website to contact. Does McCormick make a packet like this? If I have no luck finding a packet, are there any SIMPLE recipes for a stir fry sauce that people have had luck using? Thanks! Kris
