In a food processor, pulse the chickpeas until roughly chopped but not pureed.
Add the ground turkey, minced garlic, fresh parsley, ground cumin, ground coriander, sea salt, and black pepper to the processor and pulse until just combined.
Form the turkey and chickpea mixture into 4 to 5 small, flat patties.
Heat the olive 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 golden brown and cooked through.
In a small bowl, whisk together the Greek yogurt, tahini, and lemon juice until the sauce is smooth.
Serve the hot falafel patties over the diced cucumber and cherry tomatoes, drizzled with the lemon-tahini sauce.
