Preheat the oven to 425°F.
In a bowl, toss the baby potatoes with olive oil, mixed dried herbs, salt, and pepper. Spread them out on a baking sheet.
Roast the potatoes for about 25-30 minutes until they are crispy on the edges and tender inside, stirring halfway through.
Meanwhile, in a small bowl, combine lemon juice, minced garlic, a pinch of salt, and pepper.
Season the chicken breast with the lemon garlic mixture, letting it marinate briefly while the potatoes start roasting.
Heat a non-stick skillet over medium-high heat and add the chicken breast. Cook for about 4-5 minutes per side or until the internal temperature reaches 165°F.
Blanch the green beans in boiling water for 2-3 minutes until they are vibrant and tender, then drain.
Plate the sliced chicken breast alongside the roasted potatoes and green beans, drizzling any extra lemon garlic mixture over the top.
Serve warm and enjoy your balanced, flavorful meal.
