Add all apple filing ingredients to a large skillet. Mix well, then place on stove and cook over medium, high heat. Simmer until soft and thick, about 5-10 minutes. Allow to cook
Place one sheet of phyllo dough on a clean surface. Spray with cooking spray, then fold in half horizontally. Fold again horizontally to form a long rectangle. Lightly mist with cooking spray.
Place 3 tbsp of apple filling on the far left end of the dough. Fold dough over in a triangle form, like how you would fold a flag (see blog instructions). Keep folding the triangle (downwards, sideways, upwards, sideways, repeat) until all dough is used up. Tuck leftover edges under the triangle. Repeat with remaining phyllo dough.
Back at 375F degrees for 10 minutes. Filp and bake another 5 minutes. Keep an eye on them, as all oven heats differ slightly.
Optional--use a sifter to dust powdered sugar over turnovers for a pretty presentation (doesn't increase points).
