add salt to the dosa batter and mix well.
heat a mini uttapam pan( available on amazon) with four cavities, sprinkle a little oil on the tava (griddle) and wipe it off gently using a tissue.
add a little ghee or butter in each of the cavities
pour a spoonful of the batter in each of the cavities.
Mix the yoghurt/cream/mayo and sugar and now spoon it onto the batter.
sprinkle the corn, peppers and carrot over the cream.
now gently pour another spoon of the batter to cover the sandwich.
it is okay if it is messy…you can clean out the edges later.
roast on a slow flame so that the sandwich is toasted nicely.
once the lower side is done, place a blob of butter on the top and flip it.
finally, it is toasted on both sides. now you can remove from the fire.
sprinkle some grated cheese over the dosas
your cheesy dosa sandwich recipe is ready to serve
