Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large bowl, combine the sliced chicken thighs, olive oil, garlic, cumin, paprika, turmeric, cinnamon, salt, and pepper. Mix well to ensure the chicken is evenly coated with the spices.
Spread the seasoned chicken out on the prepared baking sheet in a single layer.
In the same bowl, mix together all of the ingredients for the Shawarma sauce. Drizzle the sauce over the chicken on the baking sheet.
Arrange the sliced onion, bell pepper, and zucchini around the chicken on the baking sheet.
Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the vegetables are tender.
