Preheat your oven to 400°F (200°C) and line a large rimmed sheet pan with parchment paper for easy cleanup.
Dice the chicken breast into 1-inch bite-sized pieces and chop the broccoli, red bell pepper, and zucchini into uniform sizes to ensure even cooking.
In a small mixing bowl, whisk together the extra virgin olive oil, lemon juice, lemon zest, minced garlic, dried oregano, dried thyme, sea salt, and black pepper.
Arrange the chicken and chopped vegetables on the prepared sheet pan in a single layer.
Drizzle the lemon-herb dressing over the chicken and vegetables, then toss thoroughly with tongs to coat every piece.
Roast in the center of the oven for 18 to 22 minutes, or until the chicken is cooked through and the vegetables are tender with slightly charred edges.
Remove from the oven and let rest for 5 minutes before dividing into meal prep containers for a quick and healthy weeknight meal.
