Combine first 5 ingredients; stir well. Place 1 sheet of phyllo on wax paper (keep remaining phyllo covered). Coat phyllo with cooking spray; sprinkle with 1 teaspoon sweetener. Top with 1 sheet of phyllo; coat with cooking spray, and sprinkle with 1 teaspoon sweetener. Cut stack of phyllo lengthwise into 4 equal strips, using a sharp knife. Repeat with remaining phyllo and 2 teaspoons sweetener.
Preheat oven to 375°.
Place 1 tablespoon applesauce mixture at base of 1 strip. Fold right bottom corner of phyllo over filling, making a triangle. Fold back and forth into a triangle to end of strip. Place, seam side down, on an ungreased baking sheet. Repeat with remaining phyllo strips and filling (keep covered before baking).
Combine remaining 1 teaspoon sweetener and cinnamon. Coat triangles with cooking spray; sprinkle evenly with sweetener mixture. Bake at 375° for 10 minutes or until golden. Serve warm.
