Slice the chicken breast into thin, even strips and place them in a bowl.
Toss the chicken with the ground cumin, smoked paprika, ground turmeric, sea salt, and black pepper until thoroughly coated.
Heat the extra virgin olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sauté for 6 to 8 minutes, or until the edges are golden brown and the meat is cooked through.
In a small mixing bowl, whisk together the plain Greek yogurt and lemon juice until the sauce is smooth and pourable.
In another small bowl, combine the diced cucumber, diced tomato, and minced red onion to create a fresh vegetable relish.
Place the warm cooked basmati rice in the center of a serving bowl.
Arrange the spiced chicken and the fresh vegetable relish over the rice.
Drizzle the creamy lemon-yogurt sauce over the entire bowl just before serving.
