I think its idli.
1. Each idli contains just 39 calories, which is a minimal amount in comparison to a healthy 2,000-calorie daily diet. Idlis contain no fat, no saturated fat and no cholesterol. Consuming less than 16 grams of saturated fat and 300 milligrams of cholesterol lessens your risk of cardiovascular disease and stroke.
2. And whenever you are in a hurry, idlis can be consumed quickly, if you're travelling, a plate of idlies would be perfect to consume as they are not oily and you won't feel nausea.
3. P.S: Tastes best when eaten with green chutney.
