1.In one tsp of coconut oil...fry the cumin seeds,urad dal,corriander seeds and red chillies for a min or two.
2.Put the fried spice,along with the dal and coconut in a grinder ,grind till a fairly smooth mixture is obtained,add as little water as possible.do add the salt at this stage.
3.Now toss this mixture onto the chopped cabbage and onion,mix well..shape into vadas(patties),coat with the semolina..and shallow fry.
4.Serve hot..it can be had as a snack..I served it at lunch with some rice and chicken curry.
NOTE:The original recipe also called for a bit of jaggery.I am not too crazy about adding sweet to savoury items so i didn't add it....but you please do..if you want the authentic taste of the vadas.
