Slice the chicken breast into thin, bite-sized strips.
In a small bowl, combine the cumin, paprika, turmeric, garlic powder, sea salt, and black pepper.
Toss the chicken strips with the spice blend until evenly coated.
Heat the olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sauté for 6-8 minutes, or until golden brown and cooked through.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and finely mince the red onion.
In a small ramekin, whisk together the Greek yogurt and lemon juice until creamy.
Place the warm cooked brown rice in the center of a bowl.
Arrange the spiced chicken, cucumber, tomatoes, and red onion over the rice.
Drizzle the lemon-yogurt sauce over the top and garnish with freshly chopped parsley.
