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 thoroughly with the spice mixture.
Heat the olive oil in a large skillet over medium-high heat.
Add the chicken and sauté until golden brown and fully cooked, approximately 6 to 8 minutes.
In a small ramekin, whisk together the Greek yogurt and lemon juice until smooth.
Place the warm cooked basmati rice in a serving bowl and top with the spiced chicken.
Add the diced cucumber, tomato, and red onion to the bowl.
Finish by drizzling the creamy lemon-yogurt sauce over the top before serving.
