1/2cup Greek-style yogurt (my favorite is Fage Total)
1/2cup heavy whipping cream
Instructions
Place the scallions, basil, dill, lemon juice, mustard, olive oil, garlic, salt, and pepper in the bowl of a food processor fitted with the steel blade. Puree for 15 to 20 seconds to make a smooth mixture.
Add the yogurt and heavy whipping cream and blend until smooth. Transfer the dressing to a container, cover, and refrigerate for 1 hour for the flavors to develop.
