Take a bowl and mix all the chopped (washed) vegetables in it. Add salt and pepper (as per taste)

Take a pan and heat it on stove. Meanwhile, take a two kulchas. Apply spread cheese and tomato ketchup on the one kulcha and butter on the other kulcha.

Take the vegetables which you prepared in the bowl and put them on the kulcha in which you have applied the spread cheese and tomato ketchup. Sprinkle oregano and chilli flakes. You can avoid chilli flakes if you don't like Chillis. Cover it with the other kulcha on which you applied the butter.

Put the kukchas on the pan and let it toast. Toast both the sides on low heat.

Remove it from the pan when both the sides turn golden brown. Cut it into four pieces and enjoy it with you kids and family memebers.
