Preheat and oil a griddle pan over medium heat. Remove the KING'S HAWAIIAN Original Sweet Rolls from the package keeping the loaf intact. Using a long bread knife, carefully slice the entire loaf open to create a large top and bottom set of connected rolls.
Brush the inside of the rolls with melted butter. Place the buttered side down on the griddle and toast until golden brown. Use a large spatula to flip and lightly toast the outside of the rolls.
Take the remaining melted butter and place in a large non-stick skillet on medium-high heat. Add the leftover stuffing and cook for 3-4 minutes until well browned and crispy around the edges.
Remove the toasted rolls from the griddle and spread the mayonnaise on both halves of the rolls from edge to edge.
Place the rolls on a flat surface and start with the bottom section. Evenly spread out the slices of pickle, then the Swiss cheese. Place the stuffing on top of the cheese and spread out evenly. Layer the turkey on top of the stuffing.
Spread the cranberry sauce evenly over the turkey and place the BBQ chips on top of the cranberry sauce.
Combine the shredded lettuce and the sliced radicchio in a mixing bowl. Dress with vinegar and mix well. Spread out evenly on top of the BBQ chips and top with the other half of toasted sweet rolls.
