Roast Lamb Shanks

Thaw puff pastry and cut into small squares or Christmas shapes. Arrange on a lined with parchment paper baking sheet and bake until golden according to package instructions. Garnish with orange zest. Arange sliced lamb on plates and drizzle with sauce, serve with puff pastry squares.
