Heat oven to 400°F. Line cookie sheet with cooking parchment paper.
On lightly floured surface, unroll dough. Spread mustard over dough, leaving 1/4-inch border around edges. Sprinkle corned beef, sauerkraut, cheese and caraway seed over mustard. Gently roll up dough, starting with long side. Cut into 12 (1 1/4-inch) slices. On cookie sheet, place slices, cut sides down, 2 inches apart.
Bake 17 to 18 minutes or until barely golden brown. Place spirals on serving plate; drizzle with dressing. Top each with pickle slice. Serve warm.
