In a bowl, shred the boiled chicken and add onion, capsicum, salt and black pepper powder. Give it a nice mix.

Now add mayonnaise and mix well again.

Take one bread slice and apply butter on it, now spread chicken mix on it and keep one slice of cheese on top of it. Next cover the sandwich with another bread slice.

Cut the sandwich in a desire shape. Enjoy with tomato ketchup and/ or mustard sauce.
