Peel and cube the potato, then boil in a pot of salted water until tender, approximately 12 to 15 minutes.
While the potatoes are boiling, heat a large non-stick skillet over medium heat and add the ground turkey, breaking it into small crumbles with a spatula.
Season the turkey with half of the sea salt, black pepper, rosemary, and thyme, cooking until the meat is browned and fully cooked.
Stir the fresh baby spinach into the turkey mixture until just wilted, then remove the skillet from the heat.
Drain the cooked potatoes thoroughly and return them to the warm pot.
Add the ghee, Greek yogurt, minced garlic, and the remaining salt, pepper, and herbs to the potatoes.
Mash the potatoes vigorously until they are velvety and smooth, ensuring the garlic and herbs are well incorporated.
Transfer the mashed potatoes to a bowl and top with the savory herbed turkey and spinach mixture before serving.
