Pepperoni Pinwheels

These are so light and flaky they inspire gluttony, so always double or triple this recipe or you'll be sorry! Mix the Gruyere, sage, oregano and pepper together in a small bowl. Lay the puff pastry on a lightly floured surface, with short side closest to you. Cut in half crosswise. Arrange a long side closest to you. Divide the mustard and spread evenly over the sheets of puff pastry, leaving a 1-inch border at the top edge. Divide the pepperoni and arrange in a single layer over the mustard. Top with the Gruyere mixture. Brush the farthest edge of each half with the egg. Roll the puff pastry tightly from the closest edge toward the egg-coated edge. Lay, seam side down, on a baking sheet and chill until firm, about 30 minutes. Preheat the oven to 400 degrees. Cut the logs into 1/4-inch-thick slices and arrange, cut side down, 1 inch apart on a foil- or parchment-paper-lined baking sheet. Bake, one baking sheet at a time, in the middle of the oven until golden, about 14 minutes. Serve warm.

Thaw, cut and bake as directed. --- From "Cocktail Food" by Mary Corpening Barber and Sara Corpening Whiteford with Lori Lyn Narlock (Chronicle Books, $16.95) Per serving: 36 calories (percent of calories from fat, 66), 1 gram protein, 2 grams carbohydrates, less than 1 gram fiber, 3 grams fat, 5 milligrams cholesterol, 42 milligrams sodium.
