I'm currently tucking in (a little reluctantly) to a vegan frittata or omelette made with chickpea flour and engevita.
Its okay but a bit heavy. More like a mixture between a heavy pancake that hasn't quite cooked properly and an omelette type thing. I know - I'm not selling it 
It has got potential though I think. And it's edible.
Could it be that I used besan gram flour instead of pure chickpea flour? Has anyone had any success with this?
