Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Slice the chicken breast into thin, bite-sized strips for maximum surface area and flavor.
In a medium bowl, whisk together the olive oil, lemon juice, garlic powder, cumin, paprika, turmeric, salt, and pepper.
Toss the chicken strips in the marinade until every piece is thoroughly coated.
Spread the chicken in a single layer on the baking sheet and roast for 15-18 minutes until golden brown and cooked through.
While the chicken roasts, sauté the cauliflower rice in a dry non-stick skillet over medium heat for 5 minutes until tender and slightly toasted.
Dice the cucumber and tomato, tossing them together in a small bowl to create a fresh relish.
Assemble the bowl by layering the cauliflower rice at the base, topping with the roasted chicken and vegetable relish, and finishing with a drizzle of creamy tahini.
