Slice the chicken breast into thin, bite-sized strips and place them in a medium mixing bowl.
In a small ramekin, combine the cumin, coriander, turmeric, garlic powder, smoked paprika, sea salt, and black pepper.
Sprinkle the spice blend over the chicken and toss thoroughly until every piece is evenly coated.
Heat the olive oil in a large non-stick skillet over medium-high heat.
Add the seasoned chicken to the skillet and sauté for 6 to 8 minutes, stirring occasionally, until the chicken is golden brown and cooked through.
While the chicken is cooking, prepare the sauce by whisking together the Greek yogurt, lemon juice, and dried parsley in a small bowl.
Assemble the bowl by placing the warm cooked brown rice at the base.
Arrange the cooked chicken, chopped cucumber, halved cherry tomatoes, and diced red onion over the rice.
Finish the dish by drizzling the creamy yogurt sauce over the top and serve immediately.
