Slice the chicken breast into thin, bite-sized strips.
In a medium bowl, toss the chicken strips with olive oil, cumin, coriander, turmeric, garlic powder, sea salt, and black pepper until evenly coated.
Heat a non-stick skillet over medium-high heat and add the seasoned chicken, cooking for 6-8 minutes while stirring occasionally until golden brown and cooked through.
While the chicken is cooking, chop the cucumber, tomato, and red onion into small pieces.
In a small bowl, whisk together the Greek yogurt, lemon juice, and dried parsley to create the dressing.
Assemble the bowl by placing the warm cooked brown rice at the base, topping it with the spiced chicken and the fresh vegetable mixture.
Drizzle the yogurt sauce over the entire bowl before serving.
