Drain and rinse the chickpeas, then place them in a food processor and pulse until they are coarsely chopped but still have texture.
In a medium mixing bowl, combine the ground turkey, pulsed chickpeas, chopped parsley, cumin, coriander, garlic powder, sea salt, and black pepper.
Using your hands, thoroughly mix the ingredients and form the mixture into three or four even-sized patties.
Heat the olive oil in a non-stick skillet over medium-high heat until shimmering.
Place the patties in the skillet and cook for 4 to 5 minutes per side, or until the exterior is golden brown and the internal temperature reaches 165°F.
While the patties cook, prepare the drizzle by whisking together the tahini, lemon juice, and water in a small bowl until the consistency is smooth and pourable.
Arrange the mixed greens on a plate, top with the crispy patties, and finish by drizzling the lemon-tahini sauce over the top.
