This is one of the recipes out of the countless recipes my mom used to make with the leftover idlis. I hardly have any leftovers.I usually make sixteen idlis and a few(the maximum my idly moulds along with a mini pan can hold). Its not difficult for the 4 of us to finish those for our breakfast. But I do look forward for having leftovers for trying out so many variations one can do with the leftovers. My dream came true(sounds ridiculous , I know) when I made for a get together one day and had plenty of leftovers. I stored it in the fridge and I made this for the breakfast the next day. My hubby actually loved it because he has never had idli upma. I will come up with more such recipes in future even I have to make a few extra ones!!
