01 - Preheat oven to 425°F. Line a rimmed baking sheet with parchment paper and set aside.
02 - In a large mixing bowl, combine ground turkey, zaatar, minced garlic, grated red onion, parsley, salt, pepper, egg, and breadcrumbs. Using your hands or a fork, mix until evenly incorporated without overworking the meat.
03 - With damp hands to prevent sticking, roll the mixture into 16 to 20 uniform small meatballs. Space them evenly across the prepared baking sheet.
04 - Bake for 18 to 20 minutes, flipping the meatballs halfway through, until golden brown on the outside and cooked through to an internal temperature of 165°F.
05 - While the meatballs bake, rinse rice under cold running water until the water runs clear. Transfer to a saucepan with 2 cups water and a pinch of salt. Bring to a rolling boil, then cover, reduce heat to low, and simmer for 12 to 15 minutes until liquid is absorbed. Fluff with a fork and cover to keep warm.
06 - In a small bowl, whisk together tahini, lemon juice, minced garlic, and salt. Add water gradually, whisking until the sauce reaches a smooth, pourable drizzling consistency. Thin with additional water as needed.
07 - Divide the warm rice among 4 bowls. Arrange diced cucumber, halved cherry tomatoes, sliced red cabbage, and thinly sliced red onion over each portion. Top with the baked meatballs, drizzle generously with tahini sauce, and finish with crumbled feta, fresh mint, and lemon wedges. Serve immediately.
