Step 1

Combine the onion, vinegar, sugar and salt in a small bowl. Set aside for 30 mins to soak. Drain well.

Step 2

Meanwhile, heat the oil in a large saucepan over medium-high heat. Add the sweet potato and cook, stirring, for 5 mins or until light golden. Add the cumin, coriander, cinnamon and turmeric and cook, stirring, for 30 secs or until aromatic. Add the rice and stir to combine. Add stock and stir to combine. Bring to the boil. Reduce heat to low and cook, covered, for 12 mins or until the liquid is absorbed and rice is tender. Set aside, covered, for 5 mins to steam.

Step 3

Add the lentils to the rice mixture and use a fork to gently combine. Spoon into a serving bowl. Top with the onion and sprinkle with the fetta and dukkah. Serve with flat-leaf parsley leaves.
