In a medium bowl, whisk together the Greek yogurt and mayonnaise until completely smooth.
Add the pickle juice, fresh dill, fresh chives, dried parsley, garlic powder, onion powder, salt, pepper, and lemon juice.
Whisk until fully combined and creamy.
Taste and adjust. Add more pickle juice for a tangier, brinier flavor or more lemon juice for brightness.
Use immediately or refrigerate for at least 30 minutes before serving for the best flavor.
