Pull and shred all the meat from the rotisserie chicken and place in a mixing bowl.
Add the CHA! By Texas Pete®, shredded cheddar cheese and the salt and pepper to the shredded chicken meat and mix well.
Lay out 8 slices of sandwich bread on a clean work surface.
Portion the spicy shredded chicken between 4 slices of bread followed by the tops and sandwich them down tightly.
Place the ¼ cup of butter into a cast iron skillet and turn the heat on medium.
When the butter is melted, carefully place the sandwiches into the skillet and cook them for approximately 3 minutes or each side or until golden brown, crispy and with an internal temperature of 155 degrees.
