Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Peel and cube the sweet potato into 1/2-inch pieces, slice the carrots into rounds, and chop the zucchini and broccoli into bite-sized pieces.
Cut the chicken breast into even 1-inch strips or cubes to ensure they cook at the same rate as the vegetables.
In a large mixing bowl, combine the chicken, sweet potatoes, carrots, zucchini, and broccoli.
Drizzle with extra virgin olive oil and sprinkle with dried thyme, rosemary, garlic powder, sea salt, and black pepper.
Toss everything thoroughly until the chicken and vegetables are evenly coated in the oil and herbs.
Spread the mixture in a single layer on the prepared baking sheet, ensuring nothing is overcrowded.
Roast for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the sweet potatoes are tender and golden.
Remove from the oven and serve immediately while hot.
