Slice the chicken breast into thin, bite-sized strips.
In a small bowl, combine the garlic powder, ground cumin, smoked paprika, ground turmeric, sea salt, and black pepper.
Toss the chicken strips with the spice blend until every piece is evenly coated.
Heat the olive oil in a non-stick skillet over medium-high heat and cook the chicken for 6-8 minutes until golden brown and cooked through.
While the chicken is cooking, whisk together the Greek yogurt, tahini, and lemon juice in a small ramekin until the sauce is smooth and creamy.
Dice the cucumber, halve the cherry tomatoes, and thinly slice the red onion.
Place the warm cooked rice in the bottom of a serving bowl and arrange the spiced chicken, cucumber, tomatoes, and red onion on top.
Drizzle the lemon-tahini yogurt sauce over the bowl and garnish with freshly chopped parsley before serving.
