Mix all the dry ingredients and water thoroughly. Add chopped basil. If adding vegetables to the batter, do that now.
Spray coconut oil on a heated pan. Spoon some of the chickpea mixture on 8" pan, spreading it out thin. If you need to use a spoon to spread it out, do that, but work quickly. Cook for several minutes, until it bubbles like a pancake and is golden brown. This is especially apparent with the vegan omelet sans veggies. You will be able to see when it is cooked. When it isn't done yet, it still looks wet and mushy. Flip and cook the other side. Continue with the rest of the mixture.
If adding veggies on top of chickpea omelet: Spray more coconut oil on a heated pan. Add onion. Cook for a couple of minutes. Add green pepper, and cook until tender. Add spinach, and cook until it is wilted. Put on top of chickpea omelet.
