Slice the chicken breast into thin strips and place in a bowl with the cumin, coriander, turmeric, sea salt, black pepper, and half of the lemon juice.
Heat the olive oil in a large skillet over medium-high heat and add the chicken, sautéing until the edges are golden and crispy.
In a separate small pan, lightly sauté the cauliflower rice for 3-4 minutes until tender yet still firm.
Prepare the dressing by whisking together the tahini, remaining lemon juice, and minced garlic, adding a teaspoon of water at a time until a creamy consistency is reached.
Assemble the bowl by placing the cauliflower rice and cooked quinoa at the base, then top with the cooked chicken, diced cucumber, halved cherry tomatoes, and minced red onion.
Garnish with fresh chopped parsley and drizzle the lemon-tahini sauce over the entire bowl before serving.
