In a mini food processor, combine garlic, parsley, chives, cilantro, kosher salt, lemon juice, and lemon zest. Pulse for about 30 seconds until finely chopped.

Add tahini and olive oil to the herb mixture. Pulse for 20-30 seconds until well integrated.

Gradually add cold water while pulsing continuously until the desired creamy consistency is achieved.

Taste the sauce and adjust seasoning with more lemon juice or salt if needed. Blend for 10 seconds to combine.
