Place all items into a food processor or blender and pulse until a chutney consistency is achieved.
Slowly add the oil while running the food processor or blender until it has emulsified into a dressing texture.
Remove and place into a separate container. This sauce is best enjoyed when prepared an hour before service, so the ingredients have time to incorporate all the flavor.
When the steak is sliced and plated ladle the sauce over the steak.
