what is kanji vada

I am really curious about this dish that keeps popping up in my searches called kanji vada. The other day, I was at this Indian restaurant with friends, and they ordered kanji vada, saying it’s amazing. I never tried it, but honestly, I started feeling FOMO, you know? Then I saw this picture online, and those little vadas in the bright yellow kanji looked sooo good! But like, what is kanji vada exactly? I mean, is it just a snack or something more? I heard it’s made with lentils and spices, but can you guys tell me about the flavors? I’m also wondering if I can make it at home. I’m not a super skilled cook, but I’m willing to give it a shot if it’s not too complicated. And does kanji vada have any health benefits? I like to eat healthier most of the time but man, those snacks can be hard to resist! Should I be worried about calories or is it okay to indulge a little? I think knowing what is kanji vada would help me decide on trying my hand at it! Any tips or recipes would totally be appreciated!
