Put chickpea flour, nutritional yeast, and salt in a mixing bowl and give it all a stir.
Add half of the water and stir well until it forms a smooth paste. Add the remaining water and stir again until smooth and set aside while you prepare the add-ins.
Dice up whatever veggies you want to add to your omelette. (about ¼ cup of veggies per omelette).
Add oil to a well-seasoned iron skillet or a non-stick frying pan and saute the veggies on medium-low for about 3-5 minutes until they become tender.
Remove the veggies and add them to the batter and give the batter another stir.
Turn up the heat to medium and pour the batter in the skillet like you would a large pancake and cook for about 5 minutes until the top of the omelette no longer looks wet. (You can put a lid on the frying pan for a minute or two to help it cook evenly.)
Carefully loosen up the omelette with a spatula and flip the omelette to the other side and cook for 3-5 more minutes until it is no longer soft in the middle. (Make sure there is no wet batter left in the center).
Top with cheese and fold over so that the cheese is in the middle. (You can also add a handful of baby spinach to the middle of the omelette and it will wilt with the melting cheese.) You can also add additional sauteed mushrooms or other veggies to the middle if desired.

Notes
This recipe is for 1 omelette, adjust the number of servings to the number of omelettes that you want to make.
Be sure to mix the batter first and then set it aside while you are prepping the add-ins. The chickpea batter is best when able to rehydrate for at least 10 minutes.
Make sure to use a well-oiled pan to avoid sticking.
Chickpea omelettes tend to stick to the pan, so be sure to use enough oil, allow the omelette to cook until it becomes solid, and loosen it from the bottom of the pan before flipping.
Cover the frying pan with a lid for a minute or 2 while cooking to help it cook more evenly.
Raw chickpea flour tastes terrible! Don't eat it until it's fully cooked!
