Finely chop the fresh parsley using a knife or food processor until it is minced.
In a large mixing bowl, combine the ground turkey, chickpea flour, minced parsley, ground cumin, ground coriander, garlic powder, sea salt, and black pepper.
Mix the ingredients thoroughly by hand until the herbs and spices are evenly distributed throughout the turkey.
Divide the mixture into four equal portions and shape them into small, round 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 until they are golden brown and the internal temperature reaches 165 degrees Fahrenheit.
While the patties cook, whisk together the tahini, lemon juice, and water in a small bowl until the sauce is smooth and creamy.
Transfer the crispy falafel patties to a plate and drizzle the zesty lemon-tahini sauce over the top before serving.
