Preheat oven to 400°F and line a baking sheet with parchment paper.
Slice chicken breast into thin, bite-sized strips and place in a mixing bowl.
Toss chicken with olive oil, oregano, cumin, turmeric, sea salt, and black pepper until evenly coated.
Spread chicken on the baking sheet and roast for 15-18 minutes until golden and cooked through.
While chicken roasts, steam the cauliflower rice until tender and fluff it together with the cooked quinoa.
In a small bowl, whisk together the Greek yogurt, lemon juice, and minced garlic to create a smooth sauce.
Dice the cucumber, halve the cherry tomatoes, and thinly slice the red onion.
Assemble the bowls by layering the quinoa-cauliflower mix, roasted chicken, and fresh vegetables, then drizzle with the creamy lemon sauce.
