The things you need are: chickpea flour and water. The rest is up to you! You can add whatever you have in your fridge and season however you like.
Ingredients:
5 tbsp chickpea flour
appr. 0,5 cup of water
salt, pepper, ...
Combine chickpea flour and water into a batter. If you make a thick batter (add less water), then the omlette will turn into a thicker and harder omlette, that you can easily eat from your hands. If you add half of cup or more, then it will be softer omlette. I prefere the softer one. My batter looked runny, but a lot more thicker that made with eggs.
Add whatever you like: onions, tomatoes, cheese (vegan or not), mushrooms, caparis.... Whatever you want!
Fry on both sides and enjoy!
