Rinse and drain the chickpeas, then pat them thoroughly dry with a paper towel.
In a food processor, combine the chickpeas, ground turkey, fresh parsley, garlic, cumin, coriander, sea salt, and black pepper.
Pulse the mixture until well combined but still slightly textured; avoid over-processing into a paste.
Divide the mixture into four equal portions and shape them into small, flat patties.
Heat the avocado oil in a non-stick skillet over medium-high heat.
Place the patties in the skillet and cook for 4-5 minutes per side until the exterior is golden brown and the turkey is cooked through.
While the falafel cooks, whisk together the Greek yogurt, tahini, and lemon juice in a small bowl until smooth.
Serve the warm falafel patties immediately with a generous drizzle of the zesty tahini sauce.
