Preheat oven to 400˚F and line two baking sheets with parchment or lightly grease.
On a lightly floured surface, roll the 2 sheets of puff pastry into smooth, equal rectangles.
Brush the tomato sauce over the top of one of the puff pastry sheets, leaving a 1/2 inch border around the edges. Sprinkle evenly with the shredded mozzarella. Top with the other sheet of puff pastry.
In a small bowl, beat together the egg yolk and water. Brush over the top of the puff pastry. Evenly with the
Pizza Palooza and grated Parmesan cheese.
Cut the sheet lengthwise into 9 equal long strips, then cross-wise twice to cut the strips into thirds to make 27 small sticks. Twist each stick gently while holding the two sheets together and place on the prepared baking sheet.
Bake in preheated oven until puffed and golden, about 15-20 minutes. Serve with additional tomato sauce for dipping.
