In a small bowl, whisk together the ground cumin, coriander, turmeric, garlic powder, sea salt, and black pepper.
Slice the chicken breast into bite-sized strips and toss thoroughly with the spice blend 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 brown and cooked through.
While chicken cooks, prepare the salad by tossing the diced cucumber, halved cherry tomatoes, and minced red onion in a small bowl.
In another small bowl, mix the Greek yogurt, tahini, and lemon juice until smooth to create the dressing.
Assemble the bowl by placing the cooked basmati rice at the base, topping with the spiced chicken and fresh vegetable salad.
Drizzle the creamy lemon-tahini yogurt sauce over the top before serving.
