Preheat your oven to 375°F (190°C) and line a small baking sheet with parchment paper.
Pat the turkey breast completely dry with a paper towel to ensure the herbs stick and the meat browns beautifully.
In a small bowl, whisk together the olive oil, thyme, rosemary, garlic powder, sea salt, and black pepper to create a herb paste.
Rub the herb paste evenly over all sides of the turkey breast until well-coated.
Place the turkey on the prepared baking sheet and roast for 25-30 minutes, or until the internal temperature reaches 165°F.
While the turkey is roasting, steam the fresh green beans for 5-7 minutes until they are bright green and just tender.
Toss the steamed green beans with the lemon juice and a tiny pinch of extra sea salt if desired.
Remove the turkey from the oven and let it rest for 5-10 minutes to lock in the juices before slicing thinly against the grain.
Plate the sliced turkey alongside the lemon-spritzed green beans and serve immediately.
