Preheat your oven to 425°F.
In a small bowl, mix olive oil, lemon juice, minced garlic, chopped fresh herbs, salt, and pepper.
Place the chicken breast on a baking sheet and brush generously with the lemon herb mixture.
Roast the chicken in the preheated oven for 18-20 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F.
While the chicken is roasting, toss the green beans with a drizzle of olive oil, a squeeze of lemon juice, salt, and pepper.
After the chicken has been cooking for about 10 minutes, add the green beans to a separate baking sheet and place them in the oven. Roast for 10-12 minutes until they are tender and crispy.
Once both the chicken and green beans are done, remove from the oven and let the chicken rest for a few minutes before slicing.
Serve the sliced chicken with a side of crispy green beans for a fresh, balanced meal.
