Slowly add and whisk other ingredients into the softened cream cheese to form a smooth dressing (or use blender or mixer to combine.)
Spread each side of the bread slices with about ¾ Teaspoon of Challenge Spreadable Butter; cut slices into cubes, place cubes in single layer on a shallow baking pan.
Bake in 350° oven stirring occasionally until lightly browned (about 15 minutes). Set aside to cool.
Combine dressing and drained sauerkraut and pour over kale. Stir until kale is evenly coated with dressing.
Stir in corned beef strips and grated Swiss cheese.
Add rye croutons just before serving.
With a blender the dressing goes together very quickly. If you elect to whip the dressing together, ingredients need to be added slowly into the softened cream cheese.
