4In a large bowl, combine the olive oil, lemon juice, minced garlic, ground cumin, ground paprika, ground turmeric, ground cinnamon, ground black pepper, and salt.
Add the chicken thighs to the bowl and coat them well with the marinade. Cover and refrigerate for at least 1 hour, or overnight for best results.
Preheat your grill or a large skillet over medium-high heat.
Cook the marinated chicken thighs for about 5-7 minutes on each side, or until fully cooked and slightly charred.
Remove the chicken from the grill or skillet and let it rest for a few minutes. Then, slice the chicken into thin strips.
Warm the pita breads on the grill or in a skillet for about 1-2 minutes on each side.
Assemble the shawarma by placing the sliced chicken on the warm pita breads. Top with sliced cucumbers, sliced tomatoes, sliced red onions, and drizzle with tahini sauce.
Roll up the pita breads and serve immediately. Enjoy your homemade Chicken Shawarma!
