Slice the chicken breast into thin bite-sized strips and place in a bowl.
Toss the chicken with cumin, coriander, turmeric, sea salt, black pepper, and half of the lemon juice until evenly coated.
Heat the olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-7 minutes, turning occasionally, until the edges are crispy and the meat is cooked through.
Remove the chicken from the pan and add the cauliflower rice, sautéing for 3 minutes in the remaining juices until tender.
In a small ramekin, whisk together the Greek yogurt, tahini, minced garlic, and the remaining lemon juice to create the dressing.
Construct the bowl by placing the cooked quinoa and cauliflower rice at the base.
Top with the spiced chicken, diced cucumber, halved cherry tomatoes, and thinly sliced red onion.
Drizzle the yogurt-tahini sauce over the bowl and finish with a garnish of chopped fresh parsley.
