These Spinach Ham Pastry Rolls are are large, crisp, golden, flaky pastry rolls stuffed full of chunky ham, spinach, sweet peppers and mozzarella cheese.This recipe calls for a thick chunk of ham that you can rip up with your hands to create strands and chunks rather than slices. Ask your local deli to cut a thick (2cm) chunk so that you can do this. Alternatively plan a meal involving a joint of ham (gammon) so that you can reserve a thick chunk to make these picnic rolls. As the pastry is rich and buttery, alot of fat is released during the baking of these rolls - I try to remember to line the bottom of my oven with foil to make it easier to clean. Also, take care not to burn yourself on this hot fat when removing the baking sheet from the oven.
