Slice the chicken breast into thin, bite-sized strips.
In a medium bowl, whisk together 0.5 tablespoons of olive oil, cumin, coriander, turmeric, garlic powder, sea salt, and black pepper.
Add the chicken to the bowl and toss thoroughly to ensure every piece is coated in the spice marinade.
Heat the remaining 0.5 tablespoons of olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 6 to 8 minutes, turning occasionally, until the edges are golden-brown and the meat is cooked through.
While the chicken is cooking, dice the cucumber and red onion, and halve the cherry tomatoes.
In a small ramekin, stir together the Greek yogurt and lemon juice until smooth to create the sauce.
Place the warm, cooked basmati rice in a bowl and top with the seared chicken and the fresh vegetable salad.
Drizzle the lemon-yogurt sauce over the top and serve immediately.
