Rinse the canned chickpeas thoroughly and pat them very dry with a paper towel to ensure a crispy texture.
In a food processor, combine the chickpeas, ground turkey, parsley, cilantro, garlic, cumin, coriander, sea salt, and black pepper.
Pulse the mixture until well combined but still slightly textured; avoid over-processing into a paste.
Form the mixture into 4 to 5 small, even patties, pressing firmly so they hold their shape.
Heat the olive oil in a large non-stick skillet over medium heat until shimmering.
Place the patties in the skillet and cook for 4-5 minutes per side until deeply golden brown and the turkey is cooked through.
While the falafel cooks, whisk together the Greek yogurt, tahini, lemon juice, and water in a small bowl until smooth and pourable.
Plate the warm falafel patties and drizzle generously with the lemon-tahini sauce before serving.
