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

Dust countertop and rolling pin with a little flour. Roll out pie dough to ¼-inch thickness.

Cut out 3-inch circles with a round cookie cutter or even a drinking glass. Place 1 teaspoon lemon pie filling in the center of each circle. 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 points to secure.

Place hamantaschen on prepared cookie sheets and bake for about 10-12 minutes, until just golden. 

Let hamantaschen cool then decorate as desired.  In the photo we melted white chocolate to drizzle and dip and finished with lime zest.
