Slice the chicken breast into thin, bite-sized strips for even cooking.
In a medium bowl, whisk together 0.25 tbsp of olive oil, lemon juice, minced garlic, cumin, paprika, turmeric, cinnamon, salt, and pepper.
Add the chicken strips to the bowl, tossing thoroughly to coat in the spice mixture, and let marinate for at least 10 minutes.
Heat the remaining 0.25 tbsp of olive oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and sauté until golden brown and cooked through, approximately 6 to 8 minutes.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and thinly slice the red onion.
Place the warm, cooked basmati rice into a serving bowl as the base.
Arrange the spiced chicken, cucumber, tomatoes, and red onion over the rice.
Finish by dolloping the Greek yogurt over the center and serve immediately.
