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, gently mix until all ingredients are evenly incorporated. With damp hands, roll the mixture into 16 to 20 uniform small meatballs and arrange them on the prepared baking sheet with space between each.
03 - 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.
04 - While the meatballs bake, rinse rice under cold running water until the water runs clear. Transfer to a saucepan, add 2 cups of water and a pinch of salt, then bring to a boil over medium-high heat. Cover tightly, reduce heat to low, and simmer for 12 to 15 minutes until liquid is absorbed. Remove from heat, fluff with a fork, and keep covered until ready to serve.
05 - In a small bowl, whisk together tahini, lemon juice, minced garlic, and salt. Add water one tablespoon at a time, whisking until the sauce is smooth and reaches a pourable, drizzle-friendly consistency.
06 - Divide the cooked rice among four bowls. Arrange diced cucumber, halved cherry tomatoes, sliced red cabbage, and sliced red onion over the rice in each bowl. Top with the baked meatballs, then drizzle generously with tahini sauce. Finish with crumbled feta, chopped fresh mint, and a lemon wedge on the side. Serve immediately.
