Combine shredded chicken and BBQ sauce in a small skillet over medium heat. Stir to coat and warm through, about 3 to 4 minutes. Remove from heat and set aside.
Butter one side of each slice of bread. Place all four slices, butter-side down, in a skillet or griddle over medium heat. Lay one slice of American cheese on each slice of bread.
Cook until the butter side is golden brown. Remove all the slices from the pan.
Spoon half the BBQ chicken mixture onto the cheese side of two of the slices. Add any optional toppings. Top each with a remaining slice, cheese-side down.
Cut in half and serve immediately.
