Slice the chicken breast into thin bite-sized strips and place them in a small bowl.
Toss the chicken with the cumin, coriander, turmeric, sea salt, and black pepper until evenly coated.
Heat the olive oil in a cast-iron skillet over medium-high heat and add the chicken, searing until golden and crispy on the edges.
In a small jar, whisk together the tahini, lemon juice, and minced garlic with a teaspoon of warm water until it reaches a smooth, pourable consistency.
Dice the cucumber, halve the cherry tomatoes, and finely chop the red onion and parsley, then toss them together in a small bowl.
Place the warm cooked quinoa in the base of a bowl and top with the crispy chicken and the fresh vegetable salad.
Finish the dish by drizzling the creamy lemon-garlic tahini sauce over the top.
