Slice the chicken breast into thin bite-sized strips for even cooking.
In a small mixing bowl, whisk together the olive oil, cumin, smoked paprika, turmeric, garlic powder, sea salt, and black pepper to create a marinade.
Coat the chicken strips thoroughly in the spice mixture and let them marinate for at least 5 minutes.
Heat a large non-stick skillet over medium-high heat and sauté the chicken for 6 to 8 minutes until golden brown and fully cooked.
While the chicken is browning, finely dice the cucumber, tomato, and red onion, then combine them in a small bowl to create a fresh relish.
Prepare the dressing by whisking the tahini and lemon juice together in a ramekin until smooth, adding a teaspoon of water if needed to reach a pourable consistency.
Assemble the bowl by placing the warm cooked basmati rice at the base, followed by the spiced chicken and the fresh vegetable salad.
Finish the dish by drizzling the creamy tahini sauce over the top before serving.
