Preheat your oven to 400°F and line a small rimmed baking sheet with parchment paper.
Dice the chicken breast into 1-inch cubes and chop the zucchini, bell pepper, and asparagus into bite-sized pieces.
Finely mince the garlic clove.
In a medium mixing bowl, combine the chicken cubes, zucchini, bell pepper, and asparagus.
Drizzle with olive oil and add the minced garlic, rosemary, thyme, sea salt, and black pepper.
Toss everything together until the chicken and vegetables are evenly coated in oil and spices.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the pieces are not touching for optimal browning.
Roast for 18 to 20 minutes, or until the chicken is cooked through and the vegetables are tender and slightly caramelized.
Remove from the oven and let the chicken rest for 2 minutes before serving.
