In a small bowl, whisk together the cumin, coriander, turmeric, garlic powder, sea salt, and black pepper.
Coat the chicken breast evenly with the spice mixture on all sides.
Heat the olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-7 minutes per side until the internal temperature reaches 165 degrees Fahrenheit.
While the chicken cooks, prepare the sauce by mixing the Greek yogurt with the lemon juice until smooth.
Remove the chicken from the pan and let it rest for 3 minutes before slicing into thin strips.
Place the cooked basmati rice in a bowl and top with the sliced chicken, diced cucumber, tomato, and minced red onion.
Drizzle the garlic yogurt sauce over the bowl and serve warm.
