Wash the bhindi and dry every piece completely with a kitchen towel. Let it air dry for 20 to 30 minutes if you have time. Any water left on the okra makes it slimy.
Trim off the tops and tails and cut the bhindi into thin rounds, about 1/4 inch (6 mm) thick.
Heat the oil on a tawa or wide flat pan on medium heat. Add the sliced garlic and fry for about 1 minute, until it turns light golden and fragrant.
Add the bhindi and spread it out in a thin layer. Do not cover the pan.
Cook on medium to medium-high heat for 12 to 15 minutes, stirring gently every 2 to 3 minutes, until the stickiness is gone and the edges turn crisp and slightly charred.
Add the green chillies and cook for 2 to 3 minutes more.
Sprinkle the salt at the very end, toss once and turn off the heat. Serve hot with roti or paratha.
