Preheat the oven to 400°F (200°C).
Pat the chicken breast dry and season lightly with salt and pepper.
In a small bowl, combine maple syrup with a pinch of salt and pepper to create the glaze.
Brush the chicken breast with the maple glaze, reserving a little for drizzling later.
Place the chicken on a baking sheet lined with parchment paper.
Toss the chopped carrot (if preferred, cut into sticks) and green beans with olive oil, salt, and pepper, and spread them on a separate baking sheet.
Roast the chicken for about 20-25 minutes or until the internal temperature reaches 165°F (74°C), and roast the vegetables for 15-20 minutes until tender and slightly crispy.
For extra crispiness on the green beans, you can broil them for an additional 2 minutes at the end of cooking.
Drizzle any remaining maple glaze over the chicken before serving, and plate the roasted vegetables alongside.
Enjoy your balanced, flavorful dinner!
