Preheat your oven to 400°F.
In a small bowl, combine olive oil, fresh rosemary, fresh thyme, salt, and black pepper.
Pat dry the chicken breast and rub the herb mixture evenly over it.
Place the chicken breast on a baking tray lined with parchment paper.
In a separate bowl, toss the green beans with a drizzle of olive oil, salt, and pepper.
Arrange the green beans on another baking sheet.
Place both the chicken and green beans in the oven. Roast the chicken for 20-25 minutes until fully cooked, and the green beans for 15-20 minutes until they turn crispy around the edges.
While the chicken and green beans are roasting, prepare the brown rice according to package instructions, ensuring it remains fluffy.
To serve, slice the roasted chicken breast and plate alongside the brown rice and crispy green beans.
Enjoy your balanced, nutrient-packed meal!
