Brush kaiser rolls with egg wash. Sprinkle rolls with coarse salt and caraway seeds. Bake in 350 oven for 5-10 minutes until hot. Heat roast beef in au jus until hot. Combine horseradish with mayonnaise to taste. To assemble sandwiches: split rolls, brush with horseradish mayonnaise, and pile with roast beef. These sandwiches are traditional where Dave is from!
