Toast the pine nuts until lightly browned. Set aside. Drain the chickpeas but reserve the liquid. Place the chickpeas, lemon juice, tahini, olive oil, garlic, salt, cumin, parsley and pine nuts in a food processor. Add 4 tablespoons to 2/3 cup reserved bean liquid, depending on desired texture (start with the minimum). Process until blended to the desired texture. Place the hummus in a serving dish. Sprinkle with zataar. Serve with cut up pita wedges or pita chips.
