Slice the chicken breast into bite-sized pieces and place them in a bowl with the olive oil, cumin, coriander, turmeric, garlic powder, sea salt, and black pepper.
Toss the chicken until every piece is evenly coated in the aromatic spice blend.
Heat a non-stick skillet over medium-high heat and add the chicken, cooking for 6-8 minutes until golden brown and cooked through.
While the chicken cooks, whisk together the Greek yogurt, tahini, and lemon juice in a small ramekin until the sauce is smooth and creamy.
Prepare the bowl by adding the pre-cooked warm basmati rice as the base.
Top the rice with the spiced chicken, diced cucumber, halved cherry tomatoes, and minced red onion.
Drizzle the lemon-tahini yogurt sauce over the entire bowl and garnish with freshly chopped parsley.
