Preheat your oven to 400°F.
Season the chicken breast with salt, pepper, and one tablespoon of fresh mixed herbs. Set aside.
Toss the baby potatoes with a pinch of salt and a dash of pepper. Place them in a baking dish and drizzle a small amount of olive oil over them.
Place the seasoned chicken breast and potatoes in the oven. Roast for about 25-30 minutes or until the chicken is thoroughly cooked and the potatoes are tender.
While the chicken roasts, steam the broccoli until just tender, about 5-7 minutes, then lightly toss with a little olive oil, salt, and pepper.
For the mashed potatoes, boil the baby potatoes until soft if you prefer a smoother mash. Meanwhile, heat the low-fat milk with the garlic clove (crushed) in a small saucepan to infuse the flavor.
Drain the potatoes and mash them with the infused milk and unsalted butter until smooth and creamy. Adjust salt and pepper to taste.
Plate the roasted chicken, a side of creamy garlic mashed potatoes, and the roasted broccoli. Garnish with the remaining fresh herbs for an added burst of flavor.
