In a bowl, mix 1 cup shredded chicken, 3/4 cup ketchup, 1/2 cup mayonnaise, 1/2 tsp oregano, 1/4 tsp salt and 1/2 tsp black pepper along with 1 tbs mustard if you like it.

Place a cheddar cheese slice on the bread. spread layer of chicken mixture. Now sprinkle mozzarella cheese on the top ( be generous) cover with the bread slice.

Apply soften butter on both the outer sides of the slices. make sure to cover all the slices with a thin layer of butter so it is equally grilled. Heat the pan first on low flame for 1 minute. Now place the sandwich on it ( u can grease the pan with a little butter at this point which is optional) now let the sandwich be there on very low flame and cover the pan with a lid. after a little while check if the color is changed. When the slice turn into golden brown colour flip it and grill the other side. Press lightly with a spatula . Cover the pan again and let it cook on very low flame for a while till the other side is golden brown.

Cut it into half and serve hot with any dip of mayo.

Make sure the sandwich is equally cook from both sides and keep checking because it can burn easily and you want to serve burnt sandwiches.

Must use soften butter to get equal good golden colour on the slices.

Don’t use a-lot of butter directly in the pan it can burn and in result your slices will burn too. Just grease the pan if required otherwise directly place the sandwich on the pan.
