Instructions

Preheat oven to 400°. Unfold each sheet of puff pastry. Cut each into 4 squares. Spread 1-1/2 teaspoons mustard over each square to within 1/2 in. of edges. Brush egg over edges of pastry.
On 1 corner of each square, layer ham, cheese, pear and onion. Fold opposite corner over filling, forming a triangle; press edges with a fork to seal. Transfer to ungreased baking sheets. Brush tops with remaining egg.
Bake 10-14 minutes or until golden brown. Serve warm.
Freeze option: Freeze cooled pockets in a freezer container, separating with waxed paper. To use, reheat pockets on a baking sheet in a preheated 400° oven until crisp and heated through.
