Let puff pastry sheet thaw slightly but not completely. (Puff pastry will be easier to work with if it is slightly firm.)
Blot muffaletta salad on paper towels to remove excess oil. Spread evenly over puff pastry, leaving a 1-inch border on each short side. Scatter cheeses over salad, and scatter meats over cheese.
Firmly roll up both short sides of puff pastry, meeting in the center. Using a serrated knife, cut ½-inch slices, and place 2 inches apart on prepared baking sheet.
In a small bowl, combine egg
and water, whisking to blend. Using a pastry brush, brush slices with egg wash.
Bake until golden brown, approximately 15 minutes.
Serve immediately.
Notes
*Look for jars of this Italian-style olive salad on the pickle aisle of most grocery stores. We used Alpino Authentic New Orleans Style Muffaletta.
