Peel and cube the sweet potato, then steam or boil until completely fork-tender.
Drain the sweet potato and mash thoroughly with a pinch of sea salt until smooth and creamy.
Season the turkey breast with salt and black pepper on both sides.
Heat the olive oil in a non-stick skillet over medium-high heat.
Sear the turkey breast for 5 to 6 minutes per side until golden brown and the internal temperature reaches 165°F.
Remove the turkey from the pan and let it rest while you cook the vegetables.
In the same skillet, add the green beans and a splash of water, covering for 2 minutes to steam-soften.
Remove the lid, add the minced garlic, and sauté for another 2 to 3 minutes until the beans are tender-crisp and fragrant.
Plate the turkey alongside the sweet potato mash and garlic beans, finishing with a final sprinkle of toasted sea salt.
