I was told by someone who used to work at BP;s that the dip is made from sour cream, ceasar dressing, chilies, green onions and parmesan cheese. The sour cream and dressing are about half and half and the other ingredients you have to play around with. I was surprised by the ceasar dressing but it makes sense for the taste. I ate these pretty much everyday when I was pregnant!

Hope that helps.
