Preheat oven to 375℉. Line 2 cookie sheets with parchment paper.

In a large bowl mix evoo with sugar, ¼ cup applesauce, cornstarch, vanilla extract and orange zest if using.

Add flour, baking powder and salt and mix gently until dough forms. If it is too dry and more apple sauce until dough sticks together well.

Lightly dust parchment paper with flour. Divide dough in half and roll out to ⅛-inch thickness. Cut 3-inch circles with a round cookie cutter or even a drinking glass. Fill with 1 teaspoon of your favorite filling. Fold the left side over the filling into the center, then fold the right side over and then fold the bottom up, creating a triangle. Pinch the corners to hold the shape and secure the filling.

Place cookies on the prepared cookie sheets brush with evoo and bake at 375℉ for about 15 minutes, until golden brown.
