I've done chickpea (besan, or gram flour) flour omlettes with equal parts chikpea flour and water--I used to keep a mix in the fridge where I mixed a cup of flour with 1/2 teas baking powder, and 2 Tblsp ground flax, and spices. Mix 1:1 mix and water.
I liked to saute onions, mushrooms, peppers first, remove, then add the batter, cover a minute, flip, wait till top starts getting dry, add the stuff, roll.
I love kala namak even though I didn't like eggs!
I haven't done this in so long. It was like the only thing I used that chikpea flour for !
