Mung dal with methi bhaji is a very good combination. You can use spinach leaves also instead but methi bhaji gives this dish unique flavor .
I added pickle masala also known as methya masala to it and that also gives very good taste . Oh and add some chopped onion too.
And made in instant pot. Turned out good.
Since this is dry Shaak , you can spread on bread for sandwich. Add onion , tomato and whatever else you like in your sandwich.
