Combine all above ingredients in a food processor or blender, adding only enough of the saved liquid to meet your satisfaction ( the more liquid added, the thinner the dip). Blend for 2-3 minutes to a smooth paste.Place in a small platter or shallow bowl. If preferred, sprinkle olive oil on top and garnish with parsey sprigs and lemon wedges.
To serve: Set in small dish in center of larger dish and put crudites around smaller dish, serve. Also, great as a side dip for grilled chicken. Or for a higher carb snack, add triangles of pita bread ( white or wheat) for dipping.
