Dump all of the ingredients (except the crackers) into a food processor and puree. If you are using a blender to puree, you may need to add some extra oil to facilitate blending. After blending, place in a bowl. Excess oil will rise to the edges of the bowl. Drain off.
Spread Tapenade on crisps just before serving, or let guests do it themselves.
