Preheat oven to 450°. Roll out each pastry on a lightly floured surface. Using a 2-1/2-in. round cookie cutter, cut out 12 circles from each pastry. Press rounds onto the bottoms and up the sides of greased miniature muffin cups. Prick bottoms with a fork.
Bake 8-10 minutes or until golden brown. Cool 5 minutes before removing from pans to wire racks.
In a large bowl, beat cream cheese, yogurt and confectioners' sugar until smooth. Stir in 1/2 cup lime curd. Spoon into tart shells; top with remaining lime curd. Garnish with whipped cream and lime slices if desired.
