Onions,tomatoes,garlic are tempered with Mustard seeds and curry leaves to make a delicious lowfat,spicy Chatni that goes really well with Dosas,Idlis,Vadas, Uttapams and Appams.
Use fewer Red Chilies for a milder version. The paprika is for color,add more if you like. Shallots give a more vibrant color, since they were not readily available, I used Red onions.
