Preheat your oven to 400°F. Line a baking sheet with parchment paper.
In a large bowl, combine olive oil, cumin, paprika, turmeric, garlic powder, onion powder, cinnamon, salt, and pepper. Add the chicken thighs and toss until well coated.
Place the marinated chicken on the prepared baking sheet and bake for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F.
While the chicken is baking, prepare the salad by combining cherry tomatoes, cucumber, red onion, and parsley in a bowl. Drizzle with a little olive oil and season with salt and pepper.
In a small bowl, mix the Greek yogurt with lemon juice and a pinch of salt to create a tangy sauce.
Once the chicken is done, let it rest for a few minutes before slicing it into strips.
To assemble the bowls, divide the cooked brown rice among serving bowls, top with sliced chicken, the salad mixture, and a dollop of the yogurt sauce. Serve with warm pita bread on the side.
