I found this recipe over at Kraft Foods.com...
It was really, really good. Very simple, and I only varied it by the tomatoes.
1 small can of olives (chopped)
1/4 cup chopped purple onion
1/2 cup chopped sun dried tomatoes (reconstituted), I used tomatoes in olive oil drained and patted dry.
1 brick of cream cheese
1/2 cup of sour cream
Mix together and serve (suggested) Wheat Thins. I used Staceys Pita Chips (simply naked).
Let it set for at least a hour. It is even better the next day.
