Preheat the oven to 425 degrees F.
Mix the sausage, cheese, syrup and egg white in a bowl.
Lay out the puff pastry sheets and cut in half lengthwise. Divide the meat mixture among the sheets of puff pastry, arranging in straight lines down the centers.
Whisk the egg yolk, then brush one edge of each of the four pastry sheets.
Roll the puff pastry over the sausage mixture and seal the edges. Cut each roll into 9 bite-size pieces. Transfer to two parchment-lined baking sheets. Brush the tops with the egg yolk and sprinkle over the everything seasoning.
Bake until golden brown, 18 to 20 minutes. Serve with mustard on the side. |
