Step 1

Preheat the oven to 400 degrees F and line a rimmed baking sheet with parchment.

Step 2

Unfold the puff pastry onto a lightly floured work surface. Using a rolling pin, gently roll the dough out to a 10-by-15-inch rectangle. With a small offset spatula, spread the honey mustard evenly over the dough, making sure to go all the way to the edges, then sprinkle the kielbasa pieces over the mustard.

Step 3

Starting at a long side, roll the dough into a log as you would a jelly roll, then pinch the seam shut and place onto the prepared baking sheet, seam-side down. Refrigerate the log until slightly firm, at least 30 minutes; this will make it easier to cut it into rounds. (See Cook's Note)

Step 4

Cut the chilled puff pastry log into 1/2-inch-wide slices (you should get 20 to 22 slices) and place the slices cut-side down onto the baking sheet. If needed, adjust the slice shape to form a circle. Bake until puffed and golden brown, about 18 minutes. Let cool 5 minutes before serving.
