The way I make dal is to use different vegetables for added nutrition
Well, we call it Dalma and Dal in our world is plane Dal. So in Dalma we add vegetables, but it has got specific ones - brinjal (Eggplant), pumpkin, raw banana, Taro Root (Arbi), Yam (elephant foot) , drumsticks . You can also add potato and sweet potato, papaya ( raw) if you like. Just mix it and the boil it and once it ready, give the final flavor. We add just half of a tomato while giving the final flavor. This is done at least 2-3 times in a week. Your dalma looks awesome as well. And by the way, try dal with palak once - that is my favorite.
OHHHHHHHH you know, I was feeling a little embarrassed with this thinking, well, one of my Indian friends is going to tell me I'm not doing it prperly or I've called it the wrong thing. It's definitely something I've adapted to suit my taste but there's no way I could top anything as amazing and flavourful as the dals I've had in India!!! Was sooo fascinated to hear that it's called dalma with vegetables. I sometimes roast brinjal with a little tamarind and put it on top - so good!!!! I love how versatile it is. Thanks for commenting and adding to my understanding of this amazing dish!
Most importantly the vegetables need to be cut based on how fast they boil. The ones that boils fast, should be bigger size and the one that takes more time should be smaller size. The idea is that, everything should be cooked well - that gives the best test.
