It is basically, all the ingredients you would use to make pizza... except for the crust. And to add the creaminess that makes this a dip, or more accurately a spread, you start of with a layer of herbed cream cheese. This is a great appetizer if you have friends coming over for movie night, or game night... and it is VERY filling. It easily serves a crowd of 10 people. You can add or leave out any of the ingredients to your own preferences. I prefer to add vegetables and stay away from meats, but you can add pepperoni, ham, prosciutto, or bacon.
