Drain your artichoke hearts. Add all ingredients in a food processor and whip until blended.
NOTE: You can use fresh onion and garlic. I sometimes saute them along with the drained artichokes before adding the cream cheese and lemon juice. I have found that using the powdered onion and garlic is just as good (if you are in a hurry) For those who like a little spice, a few shakes of tabasco is also good.
