Preheat your oven to 400°F (200°C).
Cut the chicken breast into small, bite-sized pieces.
In a small bowl, combine the ground cumin, paprika, turmeric, coriander, garlic powder, onion powder, cinnamon, black pepper, cayenne pepper, and salt.
Place the chicken pieces in a large bowl and drizzle with olive oil.
Sprinkle the spice mixture over the chicken and toss well to coat all pieces evenly.
Transfer the seasoned chicken to a baking sheet lined with parchment paper.
Bake the chicken in the preheated oven for 20-25 minutes, or until fully cooked and golden brown.
While the chicken is baking, cook the quinoa according to package instructions.
Once cooked, fluff the quinoa with a fork and set aside to cool slightly.
Chop the cucumber, tomatoes, and red onion into small, bite-sized pieces.
Roughly chop the fresh parsley and cilantro.
In a small bowl, whisk together tahini, lemon juice, water, olive oil, garlic powder, and cumin to make the dressing.
Once the chicken is done baking, remove it from the oven and let it rest for a few minutes.
To assemble the bowl, start with a base of cooked quinoa.
Top the quinoa with chopped cucumber, tomatoes, red onion, parsley, and cilantro.
Add baked chicken on top of vegetables.
Drizzle tahini dressing generously over entire bowl.
Serve immediately or refrigerate for later use.
