Get out and measure your ingredients.
In a mixing bowl combine mayo, sour cream, green onions, horseradish, parsley and pepper.
Blend until super creamy and oh so smooth.
Store refrigerated in an airtight container for at least 2 hours before serving and up to 3 days total. Including the day you made it.
Serve with sliced vegetables like celery, carrots, sweet peppers, cucumber, radishes, broccoli, cauliflower and so much more.
Enjoy every bite!
