Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into uniform 1-inch cubes to ensure even cooking.
Chop the zucchini into half-moons and break the broccoli into bite-sized florets.
Slice the red bell pepper into thin strips and finely mince the garlic cloves.
In a large mixing bowl, combine the chicken cubes, broccoli, zucchini, and bell pepper strips.
Drizzle the extra virgin olive oil over the mixture and add the minced garlic, rosemary, thyme, salt, and pepper.
Toss all the ingredients thoroughly until the chicken and vegetables are evenly coated with the oil and herbs.
Spread the mixture onto the prepared baking sheet in a single layer, ensuring the pieces are not overcrowded.
Roast in the oven for 20 to 25 minutes, or until the chicken is cooked through and the vegetables are tender and slightly caramelized.
Remove from the oven and serve immediately for a fresh and flavorful low-carb dinner.
