On one piece of bread, spread horseradish mayo. Layer sliced Teleme cheese and fresh basil. Top with a second piece of bread. On that slice, spread spicy brown mustard, aged cheddar and bacon. Lie third piece of bread on top. Spread your softened butter on the outside pieces of bread. Prepare second sandwich the same way.
Heat skillet to medium heat and cook the sandwich until cheese is melted on the inside. Cut sandwich in half diagonally. Enjoy!
