In a small bowl, whisk together the cumin, coriander, turmeric, sea salt, and black pepper.
Rub the spice blend onto the chicken breast until it is evenly coated on all sides.
Heat the olive oil in a medium skillet over medium-high heat and sear the chicken for 6-7 minutes per side until golden brown and cooked through.
Remove the chicken from the skillet and let it rest for 3 minutes before slicing into thin strips.
In the same skillet, lightly sauté the cauliflower rice for 2-3 minutes until tender yet still slightly firm.
Assemble the bowl by placing the cauliflower rice and cooked quinoa at the base, then top with the sliced chicken, cucumber, cherry tomatoes, and red onion.
In a small jar, whisk the tahini and lemon juice with a teaspoon of warm water until smooth, then drizzle over the bowl.
Garnish with fresh parsley and serve immediately.
