In a small bowl, whisk together 0.5 tbsp of olive oil with the cumin, coriander, turmeric, cinnamon, sea salt, and black pepper to create a spice paste.
Slice the chicken breast into thin strips and toss them in the spice paste until every piece is thoroughly and evenly coated.
Heat the remaining 0.5 tbsp of olive oil in a large skillet over medium-high heat.
Add the seasoned chicken to the hot skillet and sauté for 6 to 8 minutes, turning occasionally, until the chicken is golden brown and cooked through.
While the chicken is cooking, prepare the garlic yogurt sauce by combining the Greek yogurt, lemon juice, and minced garlic in a small ramekin.
Build your bowl by placing the warm, fluffy brown rice at the base of a shallow bowl.
Arrange the cooked chicken, diced cucumber, halved cherry tomatoes, and thinly sliced red onion on top of the rice.
Finish the dish by drizzling the creamy garlic yogurt sauce over the top and garnishing with finely chopped fresh parsley.
