In a small bowl, whisk together 0.25 tbsp extra virgin olive oil, lemon juice, garlic powder, cumin, paprika, turmeric, sea salt, and black pepper.
Slice the chicken breast into bite-sized pieces and toss in the spice marinade until well coated.
Heat the remaining 0.25 tbsp extra virgin olive oil in a skillet over medium-high heat.
Add the chicken to the skillet and cook for 6 to 8 minutes until golden brown and cooked through.
In a separate small bowl, whisk the plain Greek yogurt and tahini together until smooth to create the sauce.
Place the cooked brown rice in the bottom of a bowl as the base.
Arrange the spiced chicken, diced cucumber, halved cherry tomatoes, and sliced red onion over the rice.
Drizzle the yogurt-tahini sauce over the bowl and garnish with the chopped fresh parsley.
