01 - Gently toss fresh blueberries with honey and black pepper in a small bowl until evenly coated. Set aside to allow flavors to meld.
02 - Spread a thin, even layer of softened cream cheese on one side of each bread slice, ensuring full coverage to the edges.
03 - Distribute shredded sharp cheddar cheese over two bread slices on top of the cream cheese layer. Spoon the prepared blueberry mixture evenly over the cheddar.
04 - Place remaining bread slices cream cheese side down onto the blueberry-topped slices to form complete sandwiches.
05 - Spread softened butter generously on the outside faces of both sandwiches, ensuring even coverage for golden crisping.
06 - Heat a large skillet over medium heat. Place sandwiches in the pan and cook for 3-4 minutes per side, pressing gently with a spatula, until bread achieves deep golden brown color and cheese melts completely.
07 - Remove sandwiches from heat and let rest for 1 minute to allow cheese to set. Slice diagonally and serve immediately while hot.
