Bring blue cheese to room temperature and place it in a small mixing bowl. Smash cheese with a fork. Stir in white wine vinegar, mix well. Add olive oil and stir until blended. Season with white pepper and mix well. Stir in yogurt until well incorporated. Voila! You’ve got your dressing! Refrigerate in an air-tight container until ready to use. Will keep up to a week or so in the refrigerator.
