In a small bowl, whisk together the extra virgin olive oil, lemon juice, minced garlic, dried oregano, dried thyme, sea salt, and black pepper to create the marinade.
Place the chicken breast in a shallow dish or reusable silicone bag, pour half of the marinade over it, and let it sit for at least 20 minutes.
Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Chop the broccoli, red bell pepper, and zucchini into bite-sized pieces and place them in a mixing bowl.
Toss the vegetables with the remaining half of the marinade until evenly coated.
Arrange the marinated chicken and the vegetables in a single layer on the prepared baking sheet.
Roast for 20 to 25 minutes, or until the chicken is cooked through to an internal temperature of 165°F and the vegetables are tender.
Let the chicken rest for 5 minutes before slicing to ensure it stays juicy and flavorful.
