This was a tasty sandwich. I used Recipe #169055 for the creamy horseradish sauce and spread some on each slice of bread. I also added tomatoes. Instead of butter, I brushed the outside of the bread with mayonnaise. Next time I would also salt and pepper the filling before cooking. I do not have a panini press so I used my cast iron griddle.
