Preheat oven to 375°F (190°C).
In a non-stick skillet, cook the ground turkey over medium heat until fully browned and crumbled.
Add the baby spinach to the skillet and sauté for 2 minutes until completely wilted, then set aside to cool slightly.
In a medium mixing bowl, whisk together the egg whites, non-fat greek yogurt, feta cheese, fresh dill, garlic powder, onion powder, sea salt, and black pepper.
Stir the cooled turkey and spinach mixture into the egg white and yogurt base until well combined.
Lightly brush a small oven-safe dish with a portion of the olive oil.
Place one sheet of phyllo dough in the dish, brush lightly with oil, and top with the second sheet.
Pour the turkey and spinach filling into the center of the dough and fold the overhanging edges inward to partially cover the top.
Bake for 22-25 minutes until the phyllo is golden brown and the filling is set.
