Preheat your oven to 375°F (190°C).
Pat the turkey breast dry and rub thoroughly with olive oil, rosemary, thyme, sea salt, and black pepper.
Place the turkey in a roasting pan and cook for 25-30 minutes, or until the internal temperature reaches 165°F.
While the turkey roasts, steam the cauliflower florets in a basket over boiling water for 10-12 minutes until very soft.
Drain the cauliflower and mash with ghee and a pinch of salt until smooth and creamy.
Steam the green beans for 5-7 minutes until they are tender-crisp and vibrant green.
Once the turkey is done, remove it from the pan to rest on a cutting board.
Place the roasting pan over medium heat on the stove; whisk the arrowroot powder into the cold turkey broth and pour into the pan.
Whisk the gravy constantly, scraping up the browned bits from the bottom of the pan, until the sauce thickens into a silky consistency.
Slice the turkey breast and serve immediately with the pan gravy, mashed cauliflower, and green beans.
