Preheat your oven to 400°F.
Season the chicken breast with salt, pepper, chopped rosemary, and thyme.
Place the chicken on a baking tray and drizzle with olive oil. Roast in the oven for 20-25 minutes until cooked through and slightly golden.
Meanwhile, peel and dice the potato. Boil in lightly salted water until tender, about 15-20 minutes.
In a small saucepan, warm the low-fat milk with butter and minced garlic to infuse the flavor.
Drain the potatoes and mash them with the garlic-infused milk, adjusting seasonings with salt and pepper to taste.
For the broccoli, toss in a light drizzle of olive oil, salt, and pepper, then roast in the oven (on a separate tray) for about 15 minutes until tender and slightly crisp at the edges.
Plate the roasted chicken alongside a generous serving of creamy garlic mashed potatoes and the roasted broccoli.
Serve warm and enjoy your nutrient-packed, flavorful meal.
