Slice the chicken breast into bite-sized pieces and toss in a small bowl with the cumin, coriander, turmeric, garlic powder, sea salt, and black pepper.
Heat the olive oil in a large non-stick skillet over medium-high heat and sear the chicken until golden brown and cooked through, about 6-8 minutes.
Remove the chicken from the skillet and set aside; in the same pan, add the cauliflower rice and sauté for 3-4 minutes until tender.
In a serving bowl, combine the sautéed cauliflower rice with the pre-cooked quinoa to create a hearty base.
Top the base with the spiced chicken, diced cucumber, halved cherry tomatoes, and thinly sliced red onion.
In a small jar, whisk together the tahini and lemon juice with a teaspoon of water until creamy, then drizzle over the bowl and garnish with fresh parsley.
