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.
Coat the chicken strips evenly with the spice mixture.
Heat the olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and sauté for 6-8 minutes until golden brown and cooked through.
While the chicken cooks, whisk together the Greek yogurt and lemon juice in a small ramekin to create the sauce.
Dice the cucumber and tomato into small pieces.
Place the warm cooked brown rice in a serving bowl.
Top the rice with the sautéed chicken, diced cucumber, and diced tomato.
Drizzle the lemon-yogurt sauce over the bowl and garnish with freshly chopped parsley.
