Slice the chicken breast into thin bite-sized strips and place them in a bowl.
Toss the chicken with cumin, coriander, turmeric, garlic powder, sea salt, and black pepper until evenly coated.
Heat the olive oil in a large skillet over medium-high heat and sauté the chicken for 6-8 minutes until golden and cooked through.
While the chicken cooks, whisk the tahini with half of the lemon juice and a teaspoon of warm water until it reaches a smooth, pourable consistency.
In a small bowl, combine the diced cucumber, tomato, red onion, and parsley with the remaining lemon juice to create a fresh salad.
Place the warm cooked basmati rice in a serving bowl and top with the spiced chicken and the cucumber salad.
Drizzle the creamy tahini sauce over the entire bowl and serve immediately.
