To make croutons, cut bread into 1/2-inch cubes. Bake 15 minutes on a baking sheet at 300° F. Set aside.
Tear lettuce into a large bowl (should make about 6 cups), reserving 6 large leaves to garnish plates. Add turkey, sauerkraut and Swiss cheese; toss gently.
Divide mixture evenly and place on top of whole lettuce leaves on plates. Pour on Russian dressing, top with croutons and sprinkle with caraway seeds.
