In bowl, combine turkey, apple, cheddar, green onion and parsley.
Divide the mixture over eight of the tart shells. Brush edges of tarts with egg and top with remaining shells. Brush with egg and sprinkle each with coarse salt. Using the tip of a sharp knife, make a few ventilation slits in the top of each pie.
Bake at 400°F (200°C) until pastry is golden and filling is hot and bubbling, about 35 minutes. Let cool for 5 minutes before serving.
Tip: Leave the top tart shells in the freezer until ready to use. This will make it easier to pop them out of the foil base.
