In a small bowl, whisk together the ground cumin, coriander, turmeric, smoked paprika, sea salt, and black pepper to create the shawarma spice blend.
Slice the chicken breast into thin, bite-sized strips and toss thoroughly with the spice blend until every piece is evenly coated.
Heat the extra virgin olive oil in a skillet over medium-high heat and sauté the chicken for 6-8 minutes until golden brown and cooked through.
While the chicken is browning, prepare the garlic yogurt sauce by whisking the Greek yogurt, lemon juice, and minced garlic in a small ramekin.
Assemble the bowl by placing the cooked basmati rice at the base, then topping it with the spiced chicken, diced cucumber, tomato, and red onion.
Drizzle the creamy garlic yogurt sauce over the bowl and garnish with freshly chopped parsley before serving.
