Slice the chicken breast into thin, bite-sized strips and place them in a medium mixing bowl.
Add the ground cumin, ground coriander, garlic powder, smoked paprika, sea salt, and black pepper to the chicken, tossing until every piece is evenly coated.
Heat the olive oil in a non-stick skillet over medium-high heat until shimmering.
Add the seasoned chicken to the skillet and sauté for 6 to 8 minutes, stirring occasionally, until the edges are golden brown and the chicken is cooked through.
While the chicken cooks, whisk together the plain Greek yogurt and lemon juice in a small bowl until the sauce is smooth and creamy.
Dice the cucumber and tomato, then toss them in a small bowl with the chopped fresh parsley.
Assemble the bowl by placing the warm cooked basmati rice at the base.
Top the rice with the sautéed chicken strips and the fresh cucumber-tomato salad.
Finish the dish by drizzling the lemon-yogurt sauce over the top and serve immediately.
