Steps

• 1

  Make the mustard. In a small bowl, combine the mustard and vinegar and mix well. Cover with plastic wrap and let sit overnight at room temperature to develop the flavors.

• 2

  In a small saucepan over low heat, add the mustard, honey, and egg yolks. Cook, whisking constantly, until thickened, 7 minutes. Cool, then refrigerate until ready to serve.

• 3

  When ready to cook, set Traeger the temperature to 350°F and preheat with the lid closed for 15 minutes.

• 4

  In a medium bowl, thoroughly combine the sausage and onion.

• 5

  On a lightly floured work surface, roll each sheet of puff pastry, (there are two to a package), into an 11-inch by 10 1/2-inch rectangle. Using a pizza cutter or knife, cut each rectangle widthwise into three strips, each 3-1/2 inches wide.

• 6

  With wet hands, mold some of the sausage into a tube-like shape.

• 7

  Place the sausage in the center of one of the puff pastry strips. Wrap the pastry around the sausage and seal the seams with a bit of beaten egg. Repeat with the remaining sausage and puff pastry.

• 8

  Place the rolls seam-side down on your work surface, and brush the tops lightly with the egg.

• 9

  Cut the rolls into pieces about 1 1/2-inches long and transfer to a rimmed baking sheet lined with parchment paper, leaving about an inch between each roll.

• 10

  Place the baking sheet directly on the grill grates. Close the lid and bake until the sausage is cooked through and the pastry is golden brown, 25 minutes.
