Prepare the quinoa according to package directions and set aside.
Dice the chicken breast into bite-sized pieces and toss in a bowl with the cumin, paprika, oregano, salt, pepper, and half of the lemon juice.
Heat olive oil in a skillet over medium-high heat and sauté the chicken until golden brown and cooked through.
While the chicken is cooking, dice the cucumber, cherry tomatoes, and red onion; toss them together in a small bowl to create a fresh salad.
In a separate small bowl, whisk together the Greek yogurt, minced garlic, and the remaining lemon juice to create the garlic sauce.
Assemble the bowl by placing the cooked quinoa at the base, followed by the sautéed chicken and the cucumber-tomato salad.
Drizzle the garlic yogurt sauce over the top and garnish with chopped fresh parsley before serving.
