In a mixing bowl, combine mayonnaise and buttermilk until smooth.
Use a whisk to get a creamy texture.
Add garlic powder, onion powder, and dried dill to the mixture.
Mix well so the flavors are evenly distributed.
Stir in salt and black pepper.
Give it another thorough mix.
Fold in the chopped fresh chives and parsley.
They add a bright, fresh flavor to the dressing.
Refrigerate for at least 30 minutes before serving.
This helps the flavors meld together beautifully.
