Place stacked sheets of phyllo on a flat surface and cover with plastic wrap to keep from drying out.
Place 1 phyllo sheet on work surface. Lightly coat with nonstick cooking spray. Top with another sheet. Cut lengthwise in three 4-inch-wide strips. Move strips apart. Mound 1 heaping tablespoon filling at one end about 1-inch from corner. Fold opposite corner at same end over filling, forming a triangle. Continue folding your way up the strip, as you would a flag, to the end.
Repeat with remaining phyllo and the filling. You'll have 12 turnovers. (Can be made ahead up to this point and frozen on a tray or cookie sheet. When firm, pack in plastic bags.).
To bake freshly made or frozen turnovers: Heat oven to 400-degrees F. Lightly coat a cookie sheet with nonstick cooking spray.
Arrange turnovers seam-side down on prepared cookie sheet. Lightly spray tops with cooking spray. Sprinkle with cinnamon sugar. Bake 15 - 17 minutes, or until golden. Remove to wire rack to cool.
