Preheat your oven to 400 degrees Fahrenheit and line a small baking sheet with parchment paper for easy cleanup.
Rub the chicken breast with the olive oil and then coat all sides evenly with the dried oregano, dried thyme, garlic powder, sea salt, and black pepper.
Place the seasoned chicken on the baking sheet and bake for 18 to 22 minutes, or until the internal temperature reaches 165 degrees Fahrenheit.
While the chicken is roasting, place the broccoli florets in a steamer basket over boiling water and steam for 5 to 6 minutes until they are bright green and tender-crisp.
In a small bowl, whisk together the Greek yogurt and lemon juice until the mixture is smooth and pourable.
Allow the chicken to rest for 5 minutes before slicing it into strips, then assemble your bowl by layering the cooked quinoa, steamed broccoli, and chicken, finishing with the lemon-yogurt sauce.
