Preheat your oven to 400°F and line a small baking sheet with parchment paper.
In a small bowl, mix half of the ghee with the minced garlic, chopped rosemary, thyme, sea salt, and black pepper.
Rub the herb ghee mixture evenly over the turkey breast and place it on the baking sheet.
Toss the green beans with a tiny touch of ghee and salt, then place them on the baking sheet next to the turkey.
Roast for 20-25 minutes or until the internal temperature of the turkey reaches 165°F and the green beans are tender.
While the turkey roasts, steam the cauliflower florets until very soft, then mash with a fork or blend until creamy.
Remove the turkey from the oven and let it rest on a cutting board for 5 minutes.
To make the gravy, whisk the chicken bone broth and arrowroot powder in a small saucepan over medium heat, adding any pan drippings from the turkey.
Whisk constantly until the gravy thickens into a glossy sauce.
Slice the turkey breast and serve immediately with the cauliflower mash, green beans, and a drizzle of the pan gravy.
