Slice the chicken breast into thin bite-sized strips and place them in a bowl.
Toss the chicken with the olive oil, cumin, smoked paprika, turmeric, garlic powder, salt, and pepper until evenly coated.
Heat a non-stick skillet over medium-high heat and sear the chicken until golden brown and cooked through, approximately 6 to 8 minutes.
In a small mixing bowl, whisk together the Greek yogurt, tahini, and half of the lemon juice until the sauce is smooth and creamy.
In another bowl, combine the diced cucumber, halved cherry tomatoes, minced red onion, and chopped parsley with the remaining lemon juice.
Assemble the bowl by placing the cooked basmati rice at the bottom, then top with the spiced chicken and the fresh vegetable salad.
Drizzle the lemon-tahini yogurt sauce over the entire bowl and garnish with extra parsley if desired.
