In a food processor or mixing bowl, combine the blue cheese and a small amount of heavy cream. Blend or beat the cheese until it is smooth, creamy and easy to pipe.
Make sure the bag is fitted with a plain round tip.You can also use a plastic bag by cutting a small hole at the corner.
If you don’t have pre-pitted green olives, use an olive pitter or a cocktail pick to remove the pits, making sure to maintain the olive shape as much as possible.
Gently pipe the blue cheese mixture into each olive, being careful not to overfill them. A small amount of cheese should be visible at the opening of the olive.
If desired, you can sprinkle some cracked black pepper and diced parsley over your blue cheese-stuffed olives. Store them in your refrigerator until you’re ready to serve them.
