Slice the chicken breast into thin bite-sized strips and place them in a mixing bowl.
Toss the chicken with 0.5 tablespoons of olive oil, cumin, paprika, turmeric, garlic powder, sea salt, and black pepper until evenly coated.
Heat the remaining 0.25 tablespoons of olive oil in a large skillet over medium-high heat.
Add the seasoned chicken to the skillet and sauté for 6 to 8 minutes, turning occasionally, until the edges are golden brown and the meat is cooked through.
In a small bowl, whisk together the plain Greek yogurt and lemon juice until smooth to create the dressing.
Assemble the bowl by placing the warm cooked brown rice at the base and topping it with the sautéed chicken, diced cucumber, halved cherry tomatoes, and finely diced red onion.
Drizzle the yogurt sauce over the bowl and garnish with freshly chopped parsley before serving.
