Peel the Russet potato and cut into 1-inch cubes.
Place potato cubes in a pot of salted water, bring to a boil, and cook for 12-15 minutes until fork-tender.
While potatoes boil, heat olive oil in a skillet over medium heat and add minced garlic, sautéing for 1 minute until fragrant.
Add the ground turkey to the skillet, breaking it apart with a spatula, and cook until browned and no longer pink.
Season the turkey with half of the sea salt and black pepper, then remove from heat.
Drain the cooked potatoes and return them to the pot.
Add the ghee, Greek yogurt, and the remaining sea salt and black pepper to the potatoes.
Mash the potato mixture thoroughly until it reaches a velvet-smooth consistency.
Scoop the mashed potatoes into a bowl, top with the savory ground turkey, and garnish with fresh chives.
