In a large bowl, Stir together cream cheese and Thousand Island until smooth.
Stir in corned beef, swiss cheese, and sauerkraut.
Place a damp paper towel over egg roll wrappers so they don't dry out. Working one at a time, lay one out so that it forms a diamond in front of you. Spoon about 3 tablespoons of filling on it.
Fold up bottom and sides and roll it up, sealing the seam by rubbing some water along it and pressing it.
Heat about 1 1/2 to 2 inches of oil in a Dutch oven or deep skillet. Heat to 360 degrees.
Fry 4 egg rolls at a time until golden on both sides, about 3 minutes for each batch. Place on a paper towel-lined plate.Serve with Thousand Island dressing for dipping.
