Heat a non-stick pan on medium heat (use a round pancake pan). After it is heated, sprinkle a few drops of water on it. If the drops dry right away, the pan is ready.
Place the chapati you have just rolled on a heated pan. After about a minute, check the bottom of the chapati, if it is golden brown, and the top is translucent, flip it over.
Brush a little bit of oil on the top of the chapati, then check to see if the bottom is cooked and is golden brown.
If yes, flip the chapati over again, now brush the oil on the second side of the chapati, and turn it over again.
After about 30 seconds remove the chapati from the pan and put it on a plate and cover with a foil paper.
