First of all in a bowl add chopped onion, chopped tomato, chopped cucumber, chopped capsicum, chopped, green chillies and chopped green coriander leaves in a bowl.

Now add chaat masala, salt, roasted cumin powder and lemon juice to it and mix everything well. Now dry roast the masala papad on a pan.

Then take four breads on a chopper board. Spread butter on two breads and green sandwich chutney on the other two breads.

Now spread the prepared filling on the sandwich chutney bread. (Note :- In the filling we have taken vegetables that release their own water, so when putting the filling on the bread, take it from the bowl with a spoon so that the filling does not get watery) Now chop the roasted papad by hand and spread on top.

After that, put a slice of cheese on top and put a slice of buttered bread on it and press the bread a little.

Now spread butter on the side of the pan on which the bread is to be baked and press it lightly with a spoon until golden brown on both sides.

Now our onion tomato papad sandwich is ready to serve. Cut this sandwich in the middle with a knife and do the desired plating. I served this sandwich with special sandwich green chutney and tomato ketchup.
