Just in case, you had guests and you werent expecting anyone!! Just in case your hubby / child comes home... and asks you to fix a snack immediately !!! Heres the answer...
Learnt this age old trick from amma... "Just In Time" Recipes... where she used to make absolutely yummy snacks from the left over stuff and the basic ingredients she used to have in store....

What I used
1 cup of left over Idli / dosa batter
1 tbsp of Channa flour (kadala maavu)
1 tbsp of Rice flour
1 finely chopped onion
1 green chilli ginely chopped
A small piece of ginger finely chopped
Corriander and curry leaves.
A pinch of salt
A wee bit of crushed pepper
A few drops of oil for frying ;)
How I made it
Mix all the ingredients and taste for salt. Add a little water to thin it out, so that it is a little thicker than the idli batter. Heat the non-stick paniyaram pan. Add two or three drops of oil in each mold. Fill up 3/4 with batter and let it cook for 2 - 3 minutes until its golden brown. Use a skewer to turn it on to the other side. Add another drop of oil and let this brown for another 2 minutes. Remove and serve hot.
Serve this with tomato / mint / coconut chutney...
