Place the pastry sheets on a chopping board, make 8 triangles by cutting from corner to corner, horizontally through the middle and vertically through the middle.
Mix the ham, zucchini, cream, dill and mustard together in a bowl.
Spoon teaspoonfuls of the mixture into the centre of each triangle, then roll the triangles up leaving one end open.
Brush with milk and then bake at 200 degrees celsius (fanforced) 395F for 15-20 minutes or until golden.
Air fryer: preheat to 200 degrees celsius and airfry for 10 minutes, or until golden and crispy
