Slice the chicken breast into thin strips and place them in a bowl.
Toss the chicken with ground cumin, coriander, turmeric, garlic powder, sea salt, and black pepper until evenly coated.
Heat the extra virgin olive oil in a skillet over medium-high heat.
Add the chicken to the skillet and sear for 6-8 minutes, turning occasionally, until golden brown and cooked through.
While the chicken cooks, whisk together the tahini, Greek yogurt, and lemon juice in a small bowl to create the sauce.
In a separate small bowl, combine the diced cucumber, halved cherry tomatoes, and minced red onion.
Assemble the bowl by placing the cooked basmati rice at the base, then topping it with the seared chicken and the fresh vegetable salad.
Drizzle the creamy lemon-tahini sauce over the entire bowl and serve immediately.
