Tasty Tuesday: Dawn's Famous Ranch Dip

I don't know if this is actually Dawn's recipe, but she makes it when she comes to visit, and my Mother in Law (Dawn's mom) makes it quite a bit now too.
I made it yesterday for the U.F.O./Birthday get together and the bowl was scraped clean!
I did not use mayonnaise and it was fine. In fact the copy of the recipe I used that my MIL emailed me did not have the mayo even listed. Which is probably why I did not put it in. :)
So try it both ways and see what you like.
I served it with veggies and crackers.

Dawn's Famous Ranch Dip

Serves: 6

Mix all ingredients together and enjoy!

The version I made:
