Prepare the Buffalo Chicken:

In a mixing bowl, combine the shredded chicken with the buffalo sauce. Stir until the chicken is evenly coated. If you like it extra creamy, add the ranch or blue cheese dressing and mix well.

Assemble the Sandwiches:

Butter one side of each slice of bread. Place 4 slices of bread, buttered side down, on a cutting board or plate.

On the unbuttered side of each slice, evenly spread a layer of the shredded buffalo chicken.

Sprinkle a generous amount of shredded cheese over the chicken.

Top each sandwich with the remaining slices of bread, buttered side up.

Cook the Sandwiches:

Heat a skillet or griddle over medium heat. Place the assembled sandwiches on the skillet.

Cook the sandwiches for about 3-4 minutes on each side, or until the bread is golden brown and crispy, and the cheese is melted and gooey. Press down gently with a spatula to help the cheese melt evenly.

Serve:

Remove the sandwiches from the skillet and let them cool for a minute before slicing in half.

If desired, garnish with blue cheese crumbles, a drizzle of extra buffalo sauce, or chopped green onions for an extra kick.
