Preheat your oven to 400°F.
Prepare the chicken breast by patting it dry and seasoning generously with thyme, rosemary, garlic powder, salt, and pepper.
Place the seasoned chicken on a baking sheet and roast in the oven for 20-25 minutes or until the internal temperature reaches 165°F.
Rinse the quinoa and cook it according to package instructions, typically simmering in water for 15 minutes until fluffy.
Meanwhile, chop the broccoli, red bell pepper, and zucchini. Toss the vegetables with olive oil, salt, pepper, and a sprinkle of your favorite herbs.
Spread the vegetables on a separate baking sheet and roast them in the oven for about 15 minutes until tender and slightly charred.
Once all components are cooked, slice the chicken breast into strips and assemble your bowl by layering quinoa, roasted vegetables, and chicken.
Finish with an extra drizzle of olive oil and a light sprinkle of fresh herbs, if desired, and serve warm.
