Cut the chicken breast into bite-sized pieces and toss in a bowl with olive oil, sea salt, black pepper, oregano, garlic powder, cumin, and turmeric until evenly coated.
Heat a large skillet over medium-high heat and add the chicken, cooking for 6-8 minutes until golden brown and crispy on the edges.
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 and lightly toasted.
In a small ramekin, whisk together the tahini, lemon juice, and water until a smooth, pourable dressing forms.
Dice the cucumber, halve the cherry tomatoes, and finely mince the red onion and parsley.
Assemble the bowl by placing the cauliflower rice at the base, topping with the crispy chicken, fresh vegetables, and a generous drizzle of the lemon-tahini sauce.
