Preheat your oven to 400°F and line a large sheet pan with parchment paper for easy cleanup.
Cut the chicken breast into 1-inch cubes and chop the zucchini, bell pepper, and broccoli into similar bite-sized pieces.
Mince the garlic cloves finely.
In a large mixing bowl, combine the chicken, vegetables, and minced garlic.
Drizzle with extra virgin olive oil and sprinkle with dried oregano, dried thyme, sea salt, and black pepper.
Toss everything thoroughly until well-coated in the herb oil.
Spread the mixture in a single layer on the prepared baking sheet, ensuring it is not overcrowded.
Roast in the oven for 20 to 25 minutes, or until the chicken is cooked through and the vegetables are tender-crisp.
