Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the chicken breast into even 1-inch strips and place them in a large mixing bowl.
Chop the red bell pepper and red onion into 1-inch pieces, and trim the woody ends off the asparagus.
Add the vegetables to the bowl with the chicken, then mince the garlic and add it to the mixture.
Drizzle the extra virgin olive oil over the chicken and vegetables, then sprinkle with rosemary, thyme, sea salt, and black pepper.
Toss everything thoroughly until well-coated in the oil and herbs.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the pieces are not overcrowded.
Roast for 18-22 minutes, or until the chicken is cooked through and the vegetables are tender and slightly caramelized.
Remove from the oven and serve immediately while hot.
