Cut the bun in half, spread butter on both sides

Toast the bun on a pan. Place the ham and cheese slices on the bottom side of the bun and allow the cheese to melt

Put ½ tablespoon of butter in the pan. As it heats up, whisk the egg, salt, black pepper and chicken masala in a bowl and pour it into the pan. Let it cook to your desired preference

Once the egg is done, place it on top of your cheese and ham slices and top with the top bun.

Enjoy.
