Drain and rinse the chickpeas, then pat them dry with a paper towel to ensure a crispy texture.
In a food processor, pulse the chickpeas, parsley, cilantro, garlic, cumin, coriander, salt, and pepper until finely minced but not pureed.
Transfer the chickpea mixture to a bowl and thoroughly mix in the ground chicken until the ingredients are evenly distributed.
Form the mixture into 4 or 5 small, flat patties about half an inch thick.
Heat the olive oil in a non-stick skillet over medium heat and cook the patties for 4 to 5 minutes per side until they are golden brown and the chicken is fully cooked.
In a small bowl, whisk together the tahini and lemon juice, adding a teaspoon of warm water at a time until the sauce reaches a drizzling consistency.
Serve the falafel patties warm with the lemon-tahini sauce drizzled over the top.
