Take a bread the remove the edges and put in a plate. The apply butter on it.then thinly sliced of cucumber.put over it..then on the top put thinly sliced tomato (you can add onion,capscium,potato) whatever veggie you like..

Then sprinkle some seasoning and cover it with another bread..not its done ready to eat.note....you can apply ketchup ya green chutney on a bread and then put your veggies..my kid prefer only this one
