It is a Springfield Missouri thing and you can find it in St. Louis and Kansas City as well.
http://en.wikipedia.org/wiki/Cashew_chi ... ew_chickenI have had it and it doesn't do much for me. People in STL talk about it like it is amazing, don't get it really. Although, I am not a native so I don't get the provel cheese thing either. The first time I had it, I didn't know what it was or that I was even eating something different than mozzarella. It has an odd texture, that is for sure. Although I never got into the provel bashing that would go on in foodie circles in STL. HUGE fights would break out on forums like this about the sins of and the beauty of provel with much name calling back and forth. I figure why do I care what you like to eat? I like what I like, and you like what you like. As long as we are not stopping the other, who cares?
