Start by heating 2 tablespoons of oil in a pan. 

Once it's hot, toss in the chopped okra and fry it over medium heat until it’s lightly crisp. 

After that, take it out and set it aside.

In the same pan, pour in a tablespoon of oil. Start by tempering some cumin seeds, and then toss in the onions and sauté them until they turn a lovely golden brown. 

Next, add the garlic, ginger, and green chilli, and let everything cook together for about a minute.

Add chopped tomatoes, turmeric, red chilli powder, and coriander powder to the mix. Let it cook until the tomatoes soften up and the oil starts to separate.

Add the sautéed okra back into the pan and give it a gentle mix. 

Then, sprinkle in some garam masala, amchur, and a pinch of salt. 

Stir everything together and let it cook for another 2 to 3 minutes.
