Bring a large pot of water to a boil. Add the cabbage leaves and cook for 1–2 minutes until softened. Remove and pat dry with paper towels.
Lay each cabbage leaf flat on a clean surface. Place a slice of swiss cheese in the center, followed by corned beef and sauerkraut.
Drizzle a small spoonful of thousand island dressing over the filling.
Roll up each cabbage leaf, tucking in the sides as you go to form a wrap.
Heat a skillet over medium heat and place the wraps seam-side down. Cook for 2–3 minutes per side until the cheese melts and the wrap is heated through.
Serve warm with extra thousand island dressing on the side for dipping.
Notes
Soften the cabbage just enough: Boil the leaves only until pliable so they roll easily without tearing.
Drain the sauerkraut well: Excess moisture can make the wraps soggy and prevent proper browning in the skillet.
Don’t overfill: Keeping the filling moderate makes the wraps easier to roll and helps them hold together while cooking.
Cook seam-side down first: This helps seal the wrap and keeps it from opening in the pan.
Use medium heat: Gentle heat allows the cheese to melt fully without burning the cabbage.
Serve immediately: These wraps are best enjoyed warm while the cheese is melty and the filling is hot.
