Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish or line it with parchment paper.

Step 2

Unroll half of the crescent roll dough and press it into the bottom of the prepared dish.

Step 3

Spread Dijon mustard over the dough. Layer corned beef (or pastrami) evenly, followed by slices of Swiss cheese.

Step 4

Evenly distribute the sauerkraut on top of the cheese.

Step 5

Drizzle Russian or Thousand Island dressing over the sauerkraut.

Step 6

Unroll the remaining crescent dough and place it on top, pressing the edges to seal.

Step 7

Brush melted butter on the top layer and sprinkle with caraway seeds (optional).

Step 8

Bake for 20-25 minutes, or until the dough is golden brown.

Step 9

Remove from the oven and let cool for a few minutes. Slice into squares, garnish with parsley if desired, and serve warm.
