Whisk together 0.5 tbsp olive oil, lemon juice, minced garlic, cumin, coriander, turmeric, salt, and pepper in a medium bowl.
Slice the chicken breast into thin strips, toss in the spice marinade until well coated, and let it sit for 10 minutes.
Arrange the chicken strips on a parchment-lined baking sheet and roast at 400°F for 15-18 minutes until golden and cooked through.
While the chicken roasts, dice the cucumber, halve the cherry tomatoes, and finely chop the red onion and parsley to create a fresh salad.
In a small jar or bowl, whisk the tahini with a splash of warm water and a squeeze of lemon until it reaches a smooth, creamy consistency.
Assemble the meal by placing cooked quinoa at the base of a bowl, topping with the salad and roasted chicken, then finishing with the tahini drizzle.
