Boil edamame in salted water for 4-5 minutes, or microwave, covered for 2-3 minutes.
In a food processor, puree the edamame, yogurt, tahini, water, lemon juice, soy sauce, garlic, salt, cumin, and coriander until smooth (or as chunky as desired).
Transfer to a medium bowl and fold in parsley.*
Notes
*Visual appeal is key! Garnish with additional parsley as desired.
