Begin by preparing the chicken: In a small bowl, combine the olive oil, minced garlic, chopped fresh herbs, salt, and pepper. Rub the marinade thoroughly over the 6 oz chicken breast and let it sit for at least 15 minutes.
Preheat your grill or grill pan over medium-high heat.
Wash the baby potatoes and cut them into halves or quarters depending on size. Toss them lightly with a pinch of salt, pepper, and a drizzle of olive oil.
Place the potatoes on a baking sheet and roast in an oven preheated to 400°F for about 20-25 minutes, or until they are crisp and tender. Alternatively, you can grill them in a grill basket, stirring occasionally.
While the potatoes are roasting, grill the marinated chicken breast for about 6-7 minutes per side, or until the internal temperature reaches 165°F.
Steam or blanch the green beans in lightly salted water for about 3-4 minutes until just tender, then quickly shock in ice water to retain their vibrant color, or sauté them with a little olive oil if preferred.
Plate the grilled chicken with a serving of crispy potatoes and green beans. Enjoy your balanced meal!
