In a saucepan, heat lot of water with little oil and salt. Once boiled, add the drained rice and cook till el dente, around 7-9 minutes. Drain and reserve.
Meanwhile, in another saucepan, heat the oil/ghee. Splutter the cumin seeds and briefly fry the ginger garlic paste.
Add the onion with a little salt and saute till wilted.
Drain the tuna and add into the pan. Break the chunks using the spatula.
Add in the turmeric and red chilli powders and cook for a couple of minutes.
Now add in the cooked rice, toss lightly. Sprinkle the garam masala and the coriander leaves on the top.
Tightly close the lids with foil or cloth, to avoid steam from escaping. Keep the flame on bare minimum and allow it to be on dum for 5 minutes.
Switch off and keep undisturbed for another five minutes.
Fluff up and serve hot with raita and achaar.
Notes
I have used tuna in water. This is best to avoid any additional oil in the dish.
