<<Disclaimer: Verify this information before applying it to your situation.>> You know this list is great but... I call Tacobell's 800 number and they tell me the ingredients on their corn shells are corn flour, oil, and water. Why do I call? Because I read a post on this list stating that the same 800 # source told them there was "wheat" in them. We need to be a little more specific information when trashing a major fast food source. Is wheat listed as an ingredient or is the corn grown in the same state that someone grows wheat?
