Slice the chicken breast into thin, bite-sized strips.
In a small bowl, whisk together the cumin, coriander, turmeric, sea salt, and black pepper.
Toss the chicken strips with the spice blend until every piece is evenly coated.
Heat the olive oil in a skillet over medium-high heat and sauté the chicken until golden brown and cooked through.
In a separate small bowl, mix the Greek yogurt, lemon juice, and garlic powder to create the sauce.
Finely dice the cucumber, tomato, and red onion, then combine them in a small bowl.
Assemble the bowl by placing the cooked basmati rice at the base, topped with the spiced chicken and the fresh vegetable salad.
Drizzle the creamy garlic-yogurt sauce over the top before serving.
