Preheat oven to 350 degrees. Defrost spinach, squeeze out excess water and set aside. Let Pepperidge Farm Puff Pastry Sheets sit out of the freezer for 20 minutes before you attempt to unfold them, once ready, unfold them onto cookie sheets(one pastry per cookie sheet, but once they are rolled, you can cook them on one cookie sheet) with aluminum foil. Microwave the Rondelle cheese for about 20 seconds, to soften them up for easier spreading. Spread the cheese with a spatula onto the pastry sheets, leaving 1/2 inch border all the way around free of cheese, allowing for it to be rolled and folded later. Next, layer the thin chicken breasts on top of the cheese. Then layer the spinach on top of the chicken, then layer the ham on top of the spinach. Next, start rolling up one end of the roll to the other, when you reach the end, pull the end over the rolled part and place this side face down on the cookie sheet. Stretch and fold up the sides of the pastry to keep the food in while cooking. Once both pastries are rolled, scramble an egg and lightly baste the rolls with the egg. Cook at 350 degrees for about 30 to 45 minutes, until rolls are a medium to dark golden brown.
