Method to make the potato filling
In a pan, heat some oil. Add mustard seeds. Let them splutter.
Add cumin seeds. Then add onions. Fry the onions till transparent.
Now add the tomatoes. Fry the tomatoes till they become soft and are cooked.
Add the chopped green chilli. Add the all the spice powders mentioned above. Mix them well.
Now add the mashed potatoes. Add salt. Mix the stuffing really well. Keep on stirring on a low flame so that the mixture does not stick to the pan.
Cook for 5 minutes. Let the mixture cool before you start using it for the sandwich.
For making the sandwiches
Trim the edges of the bread
Apply amul butter evenly on the bread.
Now apply the green chutney on the bread.
Take the potato mixture and apply it on this bread. Keep  one or two onion, tomato and capsicum rings on this mixture. Sprinkle some sandwich masala or chat masala.
Now cover this potato laden bread with another slice of bread, to which both butter and chutney has been applied.
In a sandwich toaster or grill, toast or grill the sandwich till browned from both sides.
Remove and apply some butter on top of the sandwich. The butter melts. Ah….. melted butter on hot sandwich.
Its crisp from outside and spicy and soft from inside. Serve the sandwich hot with the green chutney and tomato ketchup.
