Yep. Here's mine.
3/4 cup mayonnaise
1/2 cup buttermilk
1 tablespoon minced parsley
2 teaspoons minced onion
1 to 2 garlic cloves, minced
1/2 teaspoon coarsely-ground black pepper
1/4 teaspoon salt
Splash of white vinegar
Combine all ingredients in a blender and puree until smooth. Chill at least an hour before serving. Store in the refrigerator for up to 5 days.
For a little added kick, add a chopped, de-seeded jalapeno to the blender while making the dressing.
Pain is inevitable. Suffering is Optional.
