Preheat your oven to 375°F and lightly coat a small oven-safe baking dish with a touch of oil.
In a non-stick skillet over medium heat, add the olive oil and sauté the ground turkey and minced garlic until the turkey is fully browned and crumbly.
Add the fresh spinach to the skillet and toss until completely wilted, then remove the pan from heat to cool slightly.
In a mixing bowl, combine the cooked turkey and spinach with the egg whites, crumbled feta cheese, chopped fresh dill, sea salt, and black pepper.
Lay one sheet of phyllo dough into the baking dish, allowing the edges to hang over, and repeat with the remaining sheets.
Pour the spinach and turkey mixture into the center of the phyllo layers.
Fold the overhanging edges of the phyllo dough over the top of the filling to create a rustic crust.
Bake for 25 to 30 minutes until the pastry is golden brown and the egg white filling is set.
