Peel the Yukon Gold potato and cut into 1-inch cubes.
Place the potato cubes in a pot of cold water with a pinch of sea salt, bring to a boil, and cook for 12-15 minutes until fork-tender.
While the potatoes boil, heat the olive oil in a medium skillet over medium-high heat.
Add the ground turkey to the skillet, breaking it up with a spatula, and cook until browned and fully cooked through.
Mince the garlic cloves and add them to the turkey during the last 2 minutes of cooking to infuse the meat with flavor.
Drain the cooked potatoes and return them to the warm pot to allow excess moisture to evaporate.
Add the ghee, nonfat Greek yogurt, sea salt, and black pepper to the potatoes.
Mash the potatoes using a hand masher or whisk until they reach a smooth, velvety consistency.
Finely mince the fresh chives and fold them into the mashed potatoes.
Plate the buttery garlic mashed potatoes and top with the savory garlic-infused ground turkey.
