Kadalai Maavu Masala

This quick and simple recipe  is from a TV show.I was skeptical at first trying this one , but the chef repeatedly claimed this will taste just like our Potato Masala (the one we make for Poori/Chappathi).Amazingly he was right.We liked this healthier version with out potato .
P.S : Sorry for the Not -so- good picture .I blame my camera being out of charge and had to use iPhone.
