Preheat your oven to 400°F and line a baking sheet with parchment paper.
In a food processor, pulse the rinsed chickpeas, ground turkey, parsley, minced garlic, cumin, coriander, salt, and pepper until the mixture is well combined but still retains a slightly coarse texture.
Form the mixture into 6 small patties or balls and arrange them evenly on the prepared baking sheet.
Lightly brush the top of each falafel patty with olive oil to help achieve a golden, crispy exterior during baking.
Bake for 18-20 minutes, flipping the patties halfway through, until they are cooked through and firm to the touch.
While the falafel is in the oven, whisk together the Greek yogurt, tahini, and lemon juice in a small bowl until the sauce is smooth and pourable.
Serve the warm falafel immediately, drizzled generously with the lemon-tahini sauce.
