Ingredients
Method
- Preheat the oven to 400°F. Line two large baking sheets with parchment paper.
- Arrange the Swiss cheese slices on the baking sheets, leaving at least 2 inches between each slice.
- Bake for 6–8 minutes, until the cheese is bubbling and golden around the edges.

- While the cheese bakes, mix the mayonnaise, ketchup, chopped pickle, pickle juice and mustard in a small bowl to make the dipping sauce.
- Remove the cheese from the oven. Let it cool for about 1 minute, just until flexible but no longer runny.
- Place a little chopped corned beef and dry sauerkraut along one edge of each cheese slice.

- Roll each slice snugly around the filling and place seam-side down.

- Let the roll-ups rest for 2–3 minutes to firm up. Serve warm with the dipping sauce.

Notes
Squeeze the sauerkraut very dry so the roll-ups stay crisp, and roll the cheese as soon as it is flexible but no longer runny.
