Preheat a skillet over medium-high heat.
Season the chicken breast generously with salt and pepper.
Drizzle a small amount of olive oil in the skillet and sear the chicken breast for about 5-6 minutes per side, or until the internal temperature reaches 165°F.
While the chicken is cooking, peel and dice the sweet potato into even cubes.
Boil the sweet potato cubes in a pot of water until tender, about 10-12 minutes, then drain and mash with a little pepper, and a splash of olive oil if desired.
In a separate pan, heat the remaining olive oil over medium heat, add minced garlic, and sauté until fragrant.
Add the fresh green beans and cook for 4-5 minutes until tender-crisp, seasoning lightly with salt and pepper.
Plate the seared chicken breast with a generous serving of garlic green beans and a side of sweet potato mash.
Serve immediately and enjoy a balanced, flavor-packed meal.
