In a big bowl add half of all the ingredients i.e. the onions, mushrooms, chillies, red chilli powder, turmeric, salt and eggs.
Beat with a fork till the volume doubles up.
Heat 1/2 tablespoon of oil in a non-stick pan.
Add the 2 tablespoons milk and beat again.
The pan must be hot lower the flame to minimum and add the mixture to the pan.
Swirl the pan so that the mixture spreads well. You can also use the spatula to move the egg mixture to the edges of the pan.
Here you can dip the slices of bread in the egg. Then turn the slices over. This way the slices are coated with egg on both the sides.
Once the eggs set and the mixture appears cooked in the centre carefully flip the omelette and cook on the other side.(look at notes for easy flipping techniques)
Repeat with the balance ingredients.
