Preheat oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the chicken breast into thin strips and place them in a medium mixing bowl.
In a small jar, whisk together the olive oil, lemon juice, garlic powder, cumin, paprika, turmeric, salt, and pepper.
Pour the marinade over the chicken strips and toss until every piece is evenly coated in the fragrant spice mixture.
Spread the chicken in a single layer on the prepared baking sheet and roast for 15 to 18 minutes until golden and cooked through.
Lightly sauté the cauliflower rice in a pan for 3 minutes, then stir in the cooked quinoa until heated through.
Transfer the base to a bowl, top with the roasted chicken, diced cucumber, and halved tomatoes, then finish with a dollop of yogurt.
