Recipe: Ralph's Dip

I went to a party Saturday night and brought this dip. I just got a request for the recipe, so I guess it was a hit!
I've never found it online, or in a recipe book. I got it from my sister-in-law, who got it from a neighbour named Ralph, which explains its name. I've adjusted it to use lower-fat ingredients.
Enjoy!
