In a small bowl, whisk together the cumin, coriander, turmeric, smoked paprika, sea salt, and black pepper.
Slice the chicken breast into bite-sized strips and toss with the spice blend until evenly coated.
Heat the olive oil in a skillet over medium-high heat and sauté the chicken for 6-8 minutes until golden brown and cooked through.
While the chicken cooks, whisk together the Greek yogurt, tahini, and lemon juice in a small ramekin to create the sauce.
Warm the pre-cooked brown rice and place it in the bottom of a serving bowl.
Top the rice with the spiced chicken, diced cucumber, halved cherry tomatoes, and minced red onion.
Drizzle the yogurt-tahini sauce over the bowl and garnish with fresh chopped parsley before serving.
