In a large bowl, whisk together the olive oil, apple cider vinegar, garlic, cumin, paprika, turmeric, cinnamon, salt, and pepper
Add the chicken thighs to the bowl and toss to coat with the marinade. Cover and refrigerate for at least 30 minutes or up to 2 hours.
Preheat a grill or grill pan to medium-high heat.
Grill the chicken thighs for 5-6 minutes per side, or until cooked through.
While the chicken is cooking, make the tahini sauce. In a small bowl, whisk together the tahini, water, lemon juice, olive oil, garlic, salt, and pepper until smooth.
In a large bowl, toss together the mixed greens, cherry tomatoes, cucumber, red onion, parsley, and mint.
Serve the chicken shawarma on top of the salad and drizzle with the tahini sauce. Enjoy!
