Grilled Steaks or Salmon with Basil-Pistachio Butter Recipe

In food processor or blender, combine all ingredients except steaks. Process till blended. You can chill this mixture and then form it into a roll 1" in diameter. Wrap in waxed paper and chill. When the steaks are grilled, slice the chilled butter and place on top of the hot steak, letting it melt into the meat.
