A co-worker brought spinach dip to a pot luck at work several years ago. I could not for the life of me stay out of this dip. I have had spinach dip before and liked it but there was something about this version that kept drawing me in. What was it that I could not resist about this dip? I had to find out the secret about this dip. After talking to the co-worker, I found out that it was so simple, just added one extra ingredient and that could take a good dip to over the top dip.
